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

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

This puts RPS within 1 prime of the top project!

After a very long dry period:

75*2^631091-1 (189980 digits)

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!

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

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.
