the primes > 1016 and < 10299, we use the Adleman–Pomerance–Rumely primality test (https://en.wikipedia.org/wiki/Adleman%E2%80%93Pomerance%E2%80%93Rumely_primality_test,

https://t5k.org/primes/search.php?Comment=APR-CL%20assisted&OnList=all&Number=1000000&Style=HTML), this primality test can verify the primes with such size in less than one second, see https://t5k.org/prove/prove2_1.html, and no need to use elliptic curve primality proving for the primes with such size), proof of their primality is not included here, in order to save space, larger primes can take from hours to months to prove, unless their N−1 (https://t5k.org/prove/prove3_1.html, http://bln.curtisbright.com/2013/10/09/the-n-1-and-n1-primality-tests/,

the known prime factors of N−1 or/and N+1 is ≥ the fourth root of it)) in bases b = 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 20, 21, 22, 24, 26, 28, 30, 36 (the "easy" bases (bases b with ≤ 150 minimal primes > 10299 (base b = 26 has 82 known minimal (probable) primes > 10299 and 4 unsolved families, base b = 36 has 75 known minimal (probable) primes > 10299 and 4 unsolved

known minimal (probable) primes > 10299 and 23 unsolved families))).

The large minimal primes in base b are of the form (a×bn+c)/gcd(a+c,b−1) for some a, b, c, n such that a ≥ 1, b ≥ 2 (b is the base), c ≠ 0, gcd(a,c) = 1, gcd(b,c) = 1 (i.e. they are the near-Cunningham numbers (http://factordb.com/tables.php?open=4, https://oeis.org/wiki/OEIS_sequences_needing_factors#Near_powers.2C_factorials.2C_and_primorials (sections "near-powers with b = 2" and

the numbers with large n, say n > 1000) can be easily proven primes using N−1 test (https://t5k.org/prove/prove3_1.html, http://bln.curtisbright.com/2013/10/09/the-n-1-and-n1-primality-tests/,

(if this large minimal prime in base b is xynz (where x and z are strings (may be empty) of digits in base b, y is a digit in base b) in base b, then c = 1 and gcd(a+c,b−1) = 1 if and only if the digit y is 0 and the string z is 1, and c = −1 and gcd(a+c,b−1) = 1 if and only if the digit y is b−1 and the string z is 𝜆 (the empty string (https://en.wikipedia.org/wiki/Empty_string)), if we reduce these families by removing all trailing digits y from x, and removing all leading digits y from z, to make the families be easier, e.g. family 12333{3}33345 in base b is reduced to family 12{3}45 in base b, since they are in fact the same family), except this special case (https://en.wikipedia.org/wiki/Special_case) of c = ±1 and gcd(a+c,b−1) = 1, such numbers need primality certificates to be proven primes (e.g. the prime 8957 in base b = 20 (although this prime is not minimal prime in base b = 20), its algebraic form is (161×2057−9)/19, neither N−1 nor N+1 is trivially fully factored, see https://www.mersenneforum.org/showthread.php?t=29763) (otherwise, they will only be probable primes (https://en.wikipedia.org/wiki/Probable_prime,

The Cunningham numbers bn±1 has algebraic factorization to product of the cyclotomic numbers Φd(b) with positive integers d dividing n (the bn−1 case) (see https://stdkmd.net/nrr/repunit/repunitnote.htm#repunit_factorization) or positive integers d dividing 2×n but not dividing n (the bn+1 case) (see https://stdkmd.net/nrr/repunit/repunitnote.htm#repunit_factorization), where Φ is the cyclotomic polynomial (https://en.wikipedia.org/wiki/Cyclotomic_polynomial, https://mathworld.wolfram.com/CyclotomicPolynomial.html, http://www.numericana.com/answer/polynomial.htm#cyclotomic, https://stdkmd.net/nrr/repunit/repunitnote.htm#cyclotomic, https://oeis.org/A013595, https://oeis.org/A013596, https://oeis.org/A253240) (see https://stdkmd.net/nrr/repunit/repunitnote.htm and https://doi.org/10.1090/conm/022, https://www.mersenneforum.org/attachment.php?attachmentid=7727&d=1330555980 (cached copy at https://github.com/xayahrainie4793/pdf-files-cached-copy/blob/main/pdf_7.pdf) and https://homes.cerias.purdue.edu/~ssw/cun/mine.pdf (cached copy at https://github.com/xayahrainie4793/pdf-files-cached-copy/blob/main/pdf_6.pdf) and http://homes.cerias.purdue.edu/~ssw/cun1.pdf (cached copy at https://github.com/xayahrainie4793/pdf-files-cached-copy/blob/main/pdf_71.pdf))

All prime factors of Φn(b) which are not the greatest prime factor (http://mathworld.wolfram.com/GreatestPrimeFactor.html, https://oeis.org/A006530) of n are == 1 mod n, such prime factors are exactly the prime factors of the Zsigmondy number (https://en.wikipedia.org/wiki/Zsigmondy%27s_theorem, https://mathworld.wolfram.com/ZsigmondyTheorem.html, https://oeis.org/A323748, https://oeis.org/A064078, https://oeis.org/A064079, https://oeis.org/A064080, https://oeis.org/A064081, https://oeis.org/A064082, https://oeis.org/A064083, https://oeis.org/A204847) Zs(n, b, 1), Zs(n, b, 1) = Φn(b)/gcd(Φn(b), n) (where Φ is the cyclotomic polynomial (https://en.wikipedia.org/wiki/Cyclotomic_polynomial, https://mathworld.wolfram.com/CyclotomicPolynomial.html, http://www.numericana.com/answer/polynomial.htm#cyclotomic, https://stdkmd.net/nrr/repunit/repunitnote.htm#cyclotomic, https://oeis.org/A013595, https://oeis.org/A013596, https://oeis.org/A253240) if n ≠ 2, Zs(n, 2, 1) = odd part (http://mathworld.wolfram.com/OddPart.html, https://oeis.org/A000265) of n+1, the numbers Zs(n, b, 1) are https://oeis.org/A323748, the prime factors of Zs(n, b, 1) for odd n are exactly the primitive prime factors of bn−1, the prime factors of Zs(n, b, 1) for even n are exactly the primitive prime factors of bn/2+1, also, if n is in https://oeis.org/A253235, then all prime factors of Φn(b) are == 1 mod n, since for such n, Φn(b) = Zs(n, b, 1) for all b, thus, when we do trial division (https://en.wikipedia.org/wiki/Trial_division, https://t5k.org/glossary/xpage/TrialDivision.html, https://www.rieselprime.de/ziki/Trial_factoring, https://mathworld.wolfram.com/TrialDivision.html, http://www.numericana.com/answer/factoring.htm#trial, https://www.mersenne.ca/tf1G/, https://www.mersenne.ca/tfmissed.php, https://gmplib.org/~tege/new-factors.10XXL.html, https://oeis.org/A189172) for these numbers Φn(b), we only need to do this with the prime p = the greatest prime factor (http://mathworld.wolfram.com/GreatestPrimeFactor.html, https://oeis.org/A006530) of n (for n not in https://oeis.org/A253235) and the primes p == 1 mod n.

** core(b) == 2, 3 mod 4 and n == 2×core(b) mod 4×core(b)

(if b is a perfect power (i.e. of the form mr with r > 1) (https://oeis.org/A001597, https://en.wikipedia.org/wiki/Perfect_power, https://mathworld.wolfram.com/PerfectPower.html, https://www.numbersaplenty.com/set/perfect_power/), then b must be converted to m and n must be converted to r×n, before checking whether the numbers bn−1, bn+1, Φn(b) have Aurifeuillean factorization, in fact, if b = mr and there is a prime p dividing r but not dividing n, then Φn(b) already has algebraic factorization)

Thus, ΦnL(b) is "L'n" (if core(b) == 1 mod 4) or "L'n/2" (if core(b) == 2, 3 mod 4) in the section "Algebraic Factors for an±1" in http://myfactorcollection.mooo.com:8090/calculators.html (although that page uses "a" instead of "b" for the base), and ΦnM(b) is "M'n" (if core(b) == 1 mod 4) or "M'n/2" (if core(b) == 2, 3 mod 4) in the section "Algebraic Factors for an±1" in http://myfactorcollection.mooo.com:8090/calculators.html (although that page uses "a" instead of "b" for the base), for the example of base b = 10 see https://stdkmd.net/nrr/repunit/phin10.htm (the numbers Φ20L(10), Φ20M(10), Φ60L(10), Φ60M(10), Φ100L(10), Φ100M(10), Φ140L(10), Φ140M(10), Φ180L(10), Φ180M(10), ...) and https://stdkmd.net/nrr/repunit/repunitnote.htm#aurifeuillean_repunit, also for the examples of Φn(b) with n dividing 3326400 of base b = 2 see https://web.archive.org/web/20180209113238/http://home.earthlink.net/~elevensmooth/Progress.html (the number M(6300L) is Φ6300L(2), the number M(8316M) is Φ8316M(2), the number M(9900L) is Φ9900L(2), the number M(9900M) is Φ9900M(2), the number M(13860L) is Φ13860L(2), etc.)

(note that ΦnL(b) and ΦnM(b) are always coprime (i.e. gcd(ΦnL(b), ΦnM(b)) is always 1) when they are defined)

Like ΦnL(b) and ΦnM(b), we also define Zs(nL, b, 1) = gcd(Zs(n, b, 1), ΦnL(b)) and Zs(nM, b, 1) = gcd(Zs(n, b, 1), ΦnM(b)) when b is not a perfect power (i.e. of the form mr with r > 1) (https://oeis.org/A001597, https://en.wikipedia.org/wiki/Perfect_power, https://mathworld.wolfram.com/PerfectPower.html, https://www.numbersaplenty.com/set/perfect_power/) and the cyclotomic number Φn(b) has Aurifeuillean factorization, and we have Zs(nL, b, 1) = ΦnL(b)/gcd(ΦnL(b), n) and Zs(nM, b, 1) = ΦnM(b)/gcd(ΦnM(b), n) when b is not a perfect power (i.e. of the form mr with r > 1) (https://oeis.org/A001597, https://en.wikipedia.org/wiki/Perfect_power, https://mathworld.wolfram.com/PerfectPower.html, https://www.numbersaplenty.com/set/perfect_power/) and the cyclotomic number Φn(b) has Aurifeuillean factorization. (note that n cannot be 2, since Φ2(b) cannot have Aurifeuillean factorization, the cyclotomic number Φn(b) have Aurifeuillean factorization if and only if one of the above two conditions holds, and n = 2 cannot satisfy these two conditions (since for the first condition, n must be ≥ core(b) and core(b) must be ≥ 5, and for the second condition, n must be ≥ 2×core(b) and core(b) must be ≥ 2, in both cases n cannot be 2), thus we can simply divide ΦnL(b) and ΦnM(b) by gcd(ΦnL(b), n) and gcd(ΦnM(b), n), respectively, to calculate Zs(nL, b, 1) and Zs(nM, b, 1), and we need not to use odd part (http://mathworld.wolfram.com/OddPart.html, https://oeis.org/A000265))

If b is not perfect power and separate L, M (i.e. separate Zs(nL, b, 1) and Zs(nM, b, 1)) when Zs(n, b, 1) has Aurifeuillean factorization, i.e. for odd n, bn−1 has Aurifeuillean factorization, or for even n, bn/2+1 has Aurifeuillean factorization, then every prime p not dividing b divides Zs(n, b, 1) for exactly one positive integer n (counting nL and nM instead of n when Zs(n, b, 1) has Aurifeuillean factorization, i.e. for odd n, bn−1 has Aurifeuillean factorization, or for even n, bn/2+1 has Aurifeuillean factorization), e.g. for base b = 2, the primes p = 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199, 211, 223, 227, 229, 233, 239, 241, 251, 257, 263, 269, 271, 277, 281, 283, 293, 307, 311, 313, 317, 331, 337, 347, 349, 353, 359, 367, 373, 379, 383, 389, 397, 401, 409, 419, 421, 431, 433, 439, 443, 449, 457, 461, 463, 467, 479, 487, 491, 499, 503, 509, 521, 523, 541, 547, 557, 563, 569, 571, 577, 587, 593, 599 divides Zs(n, b, 1) for n = 2, 4M, 3, 10, 12M, 8, 18, 11, 28M, 5, 36L, 20M, 14, 23, 52M, 58, 60L, 66, 35, 9, 39, 82, 11, 48, 100L, 51, 106, 36M, 28L, 7, 130, 68L, 138, 148L, 15, 52M, 162, 83, 172M, 178, 180L, 95, 96, 196M, 99, 210, 37, 226, 76L, 29, 119, 24, 50, 16, 131, 268L, 135, 92L, 70, 94, 292M, 102, 155, 156L, 316M, 30, 21, 346, 348M, 88, 179, 183, 372M, 378, 191, 388L, 44L, 200, 204L, 418, 420M, 43, 72, 73, 442, 224, 76L, 460L, 231, 466, 239, 243, 490, 166, 251, 508L, 260M, 522, 540L, 546, 556M, 562, 284M, 114, 144, 586, 148M, 299, respectively, and for base b = 3, the primes p = 2, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199, 211, 223, 227, 229, 233, 239, 241, 251, 257, 263, 269, 271, 277, 281, 283, 293, 307, 311, 313, 317, 331, 337, 347, 349, 353, 359, 367, 373, 379, 383, 389, 397, 401, 409, 419, 421, 431, 433, 439, 443, 449, 457, 461, 463, 467, 479, 487, 491, 499, 503, 509, 521, 523, 541, 547, 557, 563, 569, 571, 577, 587, 593, 599 divides Zs(n, b, 1) for n = 1, 4, 6M, 5, 3, 16, 18L, 11, 28, 30L, 18M, 8, 42L, 23, 52, 29, 10, 22, 35, 12, 78M, 41, 88, 48, 100, 34, 53, 27, 112, 126L, 65, 136, 138L, 148, 50, 78L, 162L, 83, 172, 89, 45, 95, 16, 196, 198L, 210M, 222L, 113, 57, 232, 119, 120, 125, 256, 131, 268, 30M, 69, 280, 282L, 292, 34, 155, 39, 316, 330M, 168, 173, 174M, 352, 179, 122, 186M, 378M, 191, 388, 198M, 400, 204, 209, 105, 43, 27, 146, 221, 448, 228, 460, 462L, 233, 239, 486L, 49, 166, 251, 508, 520, 58, 135, 14, 556, 281, 568, 570M, 48, 293, 592, 299, respectively.

The SNFS difficulty of Φn(b) (or ΦnL(b) or ΦnM(b)) is (no matter how much "log10 of the composite cofactor (which has no known proper factor)" is) (n−1/2×n×(n is divisible by 2)−1/3×n×(n is divisible by 3)−1/5×n×(n is divisible by 5)−1/7×n×(n is divisible by 7)−1/11×n×(n is divisible by 11 but not by 3 or 5 or 7)−1/13×n×(n is divisible by 13 but not by 3 or 5 or 7)−1/17×n×(n is divisible by 17 but not by 3 or 5 or 7))×log10(b) (note: for n divisible by 5×7 = 35, we can only minus one of "1/5×n×(n is divisible by 5)" and "1/7×n×(n is divisible by 7)", we cannot minus both; also, for n divisible by 11×13 = 143 or 11×17 = 187 or 13×17 = 221, we can only minus one of "1/11×n×(n is divisible by 11 but not by 3 or 5 or 7)" and "1/13×n×(n is divisible by 13 but not by 3 or 5 or 7)" and "1/17×n×(n is divisible by 17 but not by 3 or 5 or 7)"; also, for ΦnL(b) and ΦnM(b), the SNFS difficulty is half of it, but we cannot minus the numbers except "1/2×n×(n is divisible by 2)", unless the squarefree part of b is 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, in this case we can also minus the number 1/3×n×(n is divisible by 3), also if the squarefree part of b is 2, 3, 6, we can also minus the numbers "1/5×n×(n is divisible by 5)" and "1/7×n×(n is divisible by 7)", also if the squarefree part of b is 5, 10, 15, 30, we can also minus the numbers "1/5×n×(n is divisible by 5)", also if the squarefree part of b is 7, 14, 21, we can also minus the numbers "1/7×n×(n is divisible by 7)", see https://www.mersenneforum.org/showpost.php?p=621569&postcount=13 and https://www.mersenneforum.org/showpost.php?p=628871&postcount=4), and the GNFS difficulty of Φn(b) (or ΦnL(b) or ΦnM(b)) is just the log10 of the composite cofactor (which has no known proper factor) of Φn(b) (or ΦnL(b) or ΦnM(b), and the SNFS difficulty 3×r is equivalent to GNFS difficulty 2×r for 80 ≤ r ≤ 120 but not for all r, see https://www.mersenneforum.org/showpost.php?p=620429&postcount=50, and if the equivalent GNFS difficulty of the SNFS difficulty of Φn(b) (or ΦnL(b) or ΦnM(b)) is smaller than the GNFS difficulty of Φn(b) (or ΦnL(b) or ΦnM(b)), then SNFS is better for the number Φn(b) (or ΦnL(b) or ΦnM(b)), and if the equivalent GNFS difficulty of the SNFS difficulty of Φn(b) (or ΦnL(b) or ΦnM(b)) is larger than the GNFS difficulty of Φn(b) (or ΦnL(b) or ΦnM(b)), then GNFS is better for the number Φn(b)) (note: for quartic (degree 4) and quintic (degree 5) and octic (degree 8), the numbers are more difficult than their SNFS-size suggests, see https://www.degruyter.com/document/doi/10.1515/JMC.2007.007/pdf?licenseType=open-access (cached copy at https://github.com/xayahrainie4793/pdf-files-cached-copy/blob/main/pdf_99.pdf))
