Reserving S625 up to n=200K.
Sieve file for R625 is also available, will start working on that soon~


Plus S784 is tested up to n=400K. No prime found, releasing

R552 passed n=250K, and I am quite surprised!
I primed k=55, which removed an large amount of numbers. This gives me roughtly 12,5K tests till n=400K, minus 1066 factors found from sr2sieve. Sieve limit is P=91T, this is why i am surprised. It was quite fast i would say, lol.


Extending up to n=400K.

Both of these bases have some squared k's with partial algebraic factors that prove them always composite. After running the script to n=2.5K you can remove the following k's from the remaining file:

R537, remove k=6724.

R627, remove k=784, 81796, and 116964.

See the main Riesel page for a little more info.

Reserving S1018 to n=25K for Ian and me.


It will be started after S732 is complete in a couple of weeks.
