I am curious why someone won't do what I want
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.

Sure this version is slower than the current one, but try it. Last fiddled with by Uncwilly on 20210615 at 01:15 Reason: Generalized the link.
