34*363^103588-1 is prime!

R363 is proven. This is my first proof in years. :smile:

Unbelievably the prime is 1000 digits to short to make the top-5000 list. What a crock! :furious:

Nice to see proofs picking up again.:tu:

Bummer on the Top5000.

R331 at 15.3k. 931 k's remaining. Continuing.

[QUOTE=firejuggler;319752]i'm at n=50000 an all k
Missed the log output till n=41 000 cause of a typo ( typed -k instead of -l)
going to 100k[/QUOTE]

This only contains the prime, which doesn't do much good since you already posted it. I'll go ahead and post it complete to n=50K but can you please at least post the residues for n=41K-50K?

sorry, here it is

R268, R273, S288 are complete to n=50K

The following primes were found
[CODE]R268:
884*268^36621-1
467*268^36859-1

R273:
5890*273^44784-1

1257*288^43061+1[/CODE]Results have been emailed.
I would like to reserve R319,R327,R378 to n=50K

R354, R368, R373, and R496 are complete to n=200K, no primes were found for n=100K-200K, 1k remains on all bases, the bases are released.

R363 was proven as previously reported.

All 1k bases <= 500 are now complete to n>=200K...a significant accomplishment for the project. :smile:

gd_barnes 2012-12-12 08:16

R436 is complete to n=100K; 1 prime was found for n=50K-100K shown below; 2 k's remain; base released.

prime:
512*436^84560-1
