Isn't a new M. prime overdue?
It's a long time ago since a new Mersenne prime was found.
I'm getting a little bit 'jumpy' ... where are all the new Mersenne primes gone ;)? Last fiddled with by joblack on 20101218 at 23:07

I ran P95 for an entire 15 minutes and saw no result. Boring. What's on the telly dear? Any new trivia game shows yet? What happened to Casey in that new soap opera? Did she decide to get the operation or not? Last fiddled with by retina on 20101218 at 23:23

Not a bad idea ... But which M.prime will it be, do you think?

It is now (Dec 19th 2010) 616 days since last prime, so this is still the 4th largest prime gap (behind 897,733 and 719 days). But we are +63% above the average gap, so lets find one soon, these large gaps are EVIL!

Maybe we'll be celebrating the New Year with a New Mersenne Prime.

I have an idea of what to do but I haven't implemented it in Pari so far. might try, if you think it's worth it could there be a pattern in the step count to produce the digit root ? 8191>19>10>1 = 3 additions

in the light of GIMPS progress, there are some things we can say about this with some confidence: 1) IF one is found in 2011, it is very likely to have an exponent between 42M and 55M. 2) The probabilty of such an event is about 60,000/400,000 or 15%.

looks like all Mersenne numbers (2^x1, x not necessarily prime)>2^31 get to their digital root in a Mersenne number (2^x1, x not necessarily prime) amount of additions.
