A prime a day keeps the ills away...
789*2^5139431 is prime 
471*2^5143991 is prime

305*2^6628081 is prime

901*2^5301031 is prime!
Finally! It's been nearly two months since my last prime, and I "should" find a prime about every month at this size. This was the largest gap (in both time and n/digits) between primes I've had. :george::wacky::grin::grin::grin: July was my first month since I started NPLB that I didn't get a prime. With 159580 digits, this is my first prime that will be placed on the short list once verification is finished.

So, what does this "short list" mean anyway? What causes a prime to be on the short list? Is there some LONG list that the rest of the primes are on? (lol) Gary

Gary[/quote] The "short" list is every prime over 150,000 digits, plus smaller primes that are of special, interesting forms, while the normal list is the top 5,000 primes, plus smaller primes that are of special, interesting forms. With current primes, that means it's the top 1543 primes, plus special ones.

755*2^5149521 is prime! :grin: (From AES300 LLRnet server, in its highly profitable range of 510.5K516K.)

561*2^5157021 is prime

945*2^5157621 is prime

573*2^5158151 Helix

10 primes in an n=5500 range for n>510K. AMAZING!! What a range! :smile:
