Nice one, AES! It's always fun to pick off a nice large prime on a very low-weight k.

Within 1 of #1!...
 

2145*2^425089-1 is prime (127968 digits)

This puts RPS within 1 prime of the top project! :grin:

After a very long dry period:

75*2^631091-1 (189980 digits) :smile:

Woo hoo! This puts RPS in [URL="http://primes.utm.edu/bios/top20.php?type=project&by=PrimesRank"]first place by number of primes found[/URL]!:banana::banana::banana::banana::banana:

It's still only a tie with PIES, though, so we'll just have to find some more primes to take the lead for ourselves!

We're #1 ... we're #1
 

And HERE it is...RPS is now on top all alone! We're #1...we're #1...oh yeah!! :banana:


2145*2^430852-1 is prime (129703 digits)


k=2145 continues a remarkable run. This makes 2 primes in the last n=5K and 3 primes in the last n=16K. :cool:
