Drew, please email the results.txt file to me when you get a chance.

Will do. That won't be until Sunday night.

Aww. :(

On the bright side, GIMPS now has another chance of being the first to find the 10M+ digit prime. :)

Ok we have another chance to be the first 10 million finder ....

Once this is done, I think it is a great thing for the system and for the hush hush about the number. This is why a second program is so vital to proving that the number is indeed prime or not.

Could the p for 2^p-1 be released now?

last number in cleared exponents, cleared yesterday around 8pm

I'm no mathematician, but it would be interesting if this person's equation were even approximately accurate for, say, the next 3 Mersenne primes.

Any chance he'll post his reasoning? (Not that I'd understand it)

I've no idea if the person who claimed the above p gave M(p) prime was using some kind of heuristic, but in any event, the resulting Mersenne number isn't prime, so why would we care about what further numbers are predicted by the said heuristic, if one even exists? Heck, Fermat was way off the the mark with his "all numbers 2^2^n + 1 are prime" prediction, but he was at least correct for the first *few*. Aside from waiting for the triple-check to complete, this particular claim isn't worth any further time - that dawg just won't hunt, as a Southerner might say.

My Mlucas run of this number completed a few hours ago, and confirms the result of Drew's Prime95 run:

M37224449 is not prime. Res64: 9B2BFA3E9090EE00. Program: E2.8x

It would be fun to find a factor and eliminate it once and for all.

You are welcome to try - a few months of reasonably p-1 with somewhat deeper stage bounds than than the usual defaults would have a reasonable chance of turning up a 20 to 30-digit factor, if one exists.
