41st Mersenne Prime Found???
I've received an email claiming discovery of the 41st Mersenne prime!!
Your challenge: guess whether this report is accurate. Details: The user apparently used Ernst Mayer's mlucas program. Thus, no checksums or save files with a few iterations remaining are available. I've no idea if he used a precompiled binary. This is the user's first LL test using mlucas. The user has reported two LL results using prime95. The exponent is below M#40. I've started a verification run on our Opteron. Last fiddled with by Prime95 on 20040306 at 16:30

Dang, "I'm the one you will find M#41" should read "I'm the one who will find M#41".
I can't seem to edit the poll!

Well it is possible. I'll wait till George performs his verification.

Hmm, post the email sent to you, without the actual exponent.

If it's below M40, is it a doublecheck or is it within a million of M40?

I'd be a lot more confident in the claim if this wasn't the user's first mlucas run. The chance of a compilation mistake or mlucas setup mistake is high. I've asked the user for more output files. Ernst says mlucas produces a .stat file with interim residues. If the user has this file and it looks like real residues, then the chance this is a valid claim goes way up.

This looks promising!!
Though it's smaller than M#40 (if it's prime), I'm still very excited! :D After all, 41 known Mersenne primes is better than 40! :) Last fiddled with by ixfd64 on 20040307 at 02:06
