Large range of exponents with small P-1 bounds

JuanTutors · 2021-07-13, 01:19

I've been working on a Mersenne in the 100M digit range which has had P-1 done with very small bounds, specifically B1=100000, B2=1000000. I got curious and found that there are actually a lot of exponents in this range that have had P-1 done to these small bounds.

In these kinds of cases, should P95 be programmed to re-do P-1 when large amounts of ram are reserved?

Yes.

Does that mean that that feature is in the pipeline? Note the link I included. There are a bunch of examples in that range.

A little server work is required. P-1 bounds of 200K or more are now required to have prime95 skip P-1.
