if neither N−1 nor N+1 can be ≥ 1/4 factored (i.e. the products of the known prime factors of both N−1 and N+1 are < the fourth roots of them) but Nⁿ−1 can be ≥ 1/3 factored (i.e. the product of the known prime factors of Nⁿ−1 is ≥ the cube root (https://en.wikipedia.org/wiki/Cube_root, https://mathworld.wolfram.com/CubeRoot.html) of it) for a small n, then we can use the cyclotomy primality test (https://t5k.org/glossary/xpage/Cyclotomy.html, https://t5k.org/prove/prove3_3.html, https://t5k.org/primes/search.php?Comment=Cyclotomy&OnList=all&Number=1000000&Style=HTML, http://factordb.com/nmoverview.php?method=3) (however, this situation does not exist for these numbers, since only one of N−1 and N+1 is product of a Cunningham number and a small number, the only exception is the numbers in the family {2}1 in base b, in such case both N−1 and N+1 are products of a Cunningham number and a small number, thus for the numbers in the family {2}1 in base b, maybe factorization of N²−1 can be used)): (thus these numbers also do not need primality certificates)

(for the examples of generalized repunit primes (all generalized repunit primes base b have that N−1 is product of a Cunningham number (base b, the −1 side) and a small number (namely b/(b−1))), see https://web.archive.org/web/20021111141203/http://www.users.globalnet.co.uk/~aads/primes.html and https://web.archive.org/web/20021114005730/http://www.users.globalnet.co.uk/~aads/titans.html and https://web.archive.org/web/20131019185910/http://www.primes.viner-steward.org/andy/titans.html and http://xenon.stanford.edu/~tjw/pp/index.html)
