Newer milestone thread

The other missing exponent, 23480917, is progressing very slowly, if at all at the moment, and I don´t believe it will be finished by the end of the year. LOL...

Well, I hadn´t obviously thrown poaching into the equation...
Now I too believe it will be soon.

The active (albeit very slow) assignment is expected in a couple days.

It appears that someone also assisted this still active assignment but their result, turned in on 20 november, disagreed with the original LL test. Sometimes the excitement and drama is just too much!

Put this in your pipe and smoke it:
In the last 24 hours more DCs were completed than LLs

It's a racing certainty* that there are no more MPs before 50M

I would like to see one more discovery before I die

GIMPS will persist in the afterlife. If you go to Hell, you get a pencil and several thousand reams of paper. And a 1977-vintage eight-digit calculator. If you go to Heaven, you get a quantum computer. Very simple.

(Or you get up there and you find out that we've been thinking of numbers the wrong way this whole time, and that there is a simple generating sequence for all primes. We'd have found it centuries ago, but for the fact that we allowed our 10 fingers to keep us slaves to base 10...)

The pencil has no eraser. You are assigned MM127.

I shall concentrate the optimal TF effort on the exponent in hand.

And they are pretty old-school about things: All residues are reported in Roman numerals.

So? Where is the problem? He has all the eternity for it...

And at least the heating comes free

[bcp19]

That's why you can't use computers, could you imagine the errors induced in that much heat?

From the MersenneWiki entry on M127:

there is no hope of running a primality test on this number anytime in the foreseeable future. (It would take about 4,700,000,000,000,000,000,000,000,000,000,000 GHz-days to run the Lucas-Lehmer test on that number. Having the top 250 supercomputers working together at full power on this, it would take 161,600,000 times as long as the universe has existed.)
