Lucas(148091) is certificated to be prime in September 2015 (see prime pages), but why no one certificate Fibonacci(148091)? Fibonacci(148091) is smaller than Lucas(148091), and 148091 may be the largest n such that Fibonacci(n) and Lucas(n) are both primes.

I am curious that why none has reserved the Wagstaff number (2^95369+1)/3, it has only 28709 digits, much smaller than the partition number Partition(1289844341) (40000 digits), which is already reserved and proven to be prime (see http://www.ellipsa.eu/public/primo/top20.html), and Wagstaff numbers are much more important (and seems to be easier to be proven prime) than partition numbers.

More attacks on our hard efforts! "Only 28709 digits" -- have you tried running Primo, even at 10k digits? it is O(log(n)^(4+eps)). It is not trivial to do such certifications. It is absurd to say that Wagstaff is "much more important" than a partition number. The latter has greater entropy and show off the effectiveness of ECPP. There are couple of aims here: big ECPP and proving classic top20 PRPs. We aim to do both. Please stop harping on about our efforts and start doing some Primo work.
