Ian,

If you are so inclined, R746 is now another 2ker that needs to be taken to n=100K. Details will be available when the pages are back up, which could be late Sat. There is a sieve file on the reservations page for n=50K-100K.

I'm listening to a song called "Episode 666" plus I realize R666 is a 1-ker waiting to get proven. So It' reserved now. :smile:
