[QUOTE=chalsall;327767]Amusingly, this exponent passed through two ANONYMOUS assignments before finally being picked up by Curtis on 2012-12-12 -- one assignment on 2012-08-14 which then expired 60 days later, then another on 2012-10-13 which expired 60 days later.

Neither had done a single cycle on it. Or, at least, not reported.[/QUOTE]

Tsk. Accidental assignments to inattentive Stress Testers? (i.e. those who don't pay attention to the choices on the first run of P95.)

Does Curtis use a formula? Maybe smooth p-1 and chunky p+1? :smile:

Well done everybody! Congratulations to discoverer, developers, helpers, etc.

Drink that champagne and let's move on to the next!

Arrr... I will sleep better now...

The 43M bits prime (**) it showed up suddenly as the 10M+ prime number, if i remember well.

Undoubtfully Curtis would've tested that one had not someone else taken it.

So for payout of the money, i didn't check conditions carefully, is it allowed to keep secret a trick?

edit: it is not beyond reasonable doubt now that pay out - i would ask for my money back
(**) edit2 : whatever the trick is

That's James', not mine.

And, before anyone points out that the prime also isn't listed on Mersenne.info, that will update at about 0700 UTC tomorrow.
