Prime95 2018-12-09 14:52

Lucky 13 (M51 related)
 
On Dec 7th, a new Mersenne prime was reported. I emailed the discoverer, obtained the last save file, and reran the last 100,000 iterations. Sure enough, we have a new prime!

Aaron has started a full test using prime95, but that doesn't count as an official double-check. We need a volunteer to run CudaLucas and/or mlucas.

As usual, the automatic email notification to myself and past Mersenne prime discoverers failed. Yes, the automatic email was debugged and tested after its last failure. Apparently bit rot set in. Fortunately the backup notification plan worked.

Nice hint :smile: It reminds me of the quote from Stephen King's "The Dark Tower" series:

"There are other worlds than these"


I am ready to test with CUDALucas, Mlucas etc.

Congratulations to discoverer!
Curtis Cooper is discoverer or not?

Quite astonishing!
How many more of these finds do we need before statistical cluster analysis lets us suspect that some as yet undiscovered mechanism is at work here making mersenne numbers more likely to be prime than was previously thought?

Nice.

Congratulations!

DoubleMersennes.org (l.morelli at moreware.org) is silently waiting to know the exponent to start what could be considered a lengthy sieving process before updating the tables.

Congratulations!

Congratulations!

I wonder if someone like Terence Tao could be intrigued into a review of the MP distribution heuristic, finally? :rolleyes:

I wonder if the exponent is congruent to 1 or to 3 (mod 4)?

There is a somewhat improbable imbalance in favor of the 1's.
