[QUOTE=airsquirrels;475350]Worth mentioning, the gpuOwl verification did complete successfully in record time! (Thanks Preda!)

Max ROE was 0.38.[/QUOTE]
Kind of giving away the range (at least, the limit) isn't it?
(sorry, I am far behind with the reading and news due to the winter holidays..., but I am catching up)

[QUOTE=Mark Rose;475367]So if you wanted to print the full decimal expansion on US letter sheets at 6 point size with ½" margins, it would take approximately 2500 pages.[/QUOTE]

[QUOTE=Mark Rose;475374]I guess if I double-sided it, it would take only 1250 pages. I forgot you could do that with paper haha[/QUOTE]
Wrong, it will still take 2500 pages, but only 1250 sheets of paper... :razz:

Oops! I meant -2

Another thing that can be a bit confusing, is that sometimes [$]M_n[/$] is used to mean [$]2^n - 1[/$], while at other times it is used to mean the [$]n[/$]th entry in the sorted vector [$](2^2-1,2^3-1,2^5-1,2^7-1,2^{13}-1,\ldots )[/$] of all existing Mersenne primes, and sometimes it is meant to mean the [$]n[/$]th entry in the list of currently known primes, sorted by either size or discovery date.

When I saw [$]M_3[/$], I thought of [$]7[/$], not [$]31[/$].

You are right. Although I believe the expression M(3)=7

Following this while on lazy holiday was quite exciting.

But did I miss something? M51 also discovered?

No way :smile:

[QUOTE=MacPrime;476123]M51 is already discovered and I will announce M50 and M51 together tomorrow GMT 08:00, Jan 04.

Yes, a strange post. But that user's first post was actually pretty valuable, alerting us to [URL="http://mersenneforum.org/showthread.php?t=22501"]previously unknown factors in FactorDB[/URL]. So... who knows what prompted this.

I dont think that he had an other Mersenne prime, maybe just a false positive.
