Merry Christmas and a prime! (M50 related)

[pacionet]

I try with M77324641

[MushNine]

I thought the residue would be a string of zeroes for a prime. None of Jon's residue are such. So I suppose it's been removed from public record.

If i remember correctly, the server writes a "masked" residue for a probable prime.

Just finished my double-check:
Mxxxxxxxx is prime!

Looks like we have a winner, but my run was using the same Prime95 as the first result and I don't know if George will want to wait for the pending cudalucas check before making the exponent public. Traditionally I think that was the process.

I saved the interim partial residues every 1M iterations (starting at 36M since I forgot at first) so we'll be comparing the cudalucas run along the way.

But...yeah, the "Boxing Day Prime" looks good!

I think we can say "Probably found M50 : it is ..." .
Come on. :)

I didn't believe GIMPS would ever find another one.

We know the exponent is above 36 million now. There I was thinking it might have been the result of a triple check of a mistakenly verified test from years and year ago.

... higher than the last one ;)

I hope this forum will be the first to know the newly discovered prime! Come on!

Well we already knew that from earlier posted information. Ernst posted it would take at 72 hours to complete a run at 4 ms/iter, meaning it would be at least around 64 million.

I found Madpoo test, the prime could be M64764893 :) which seems have 3 LL (1 failed e 2 OK)

Maybe a decoy?
