FYI


It looks like we're going to let GFN-22 run out of work when it reachs b=400K. It will be suspended there until we find a GFN-21, and then it will resume.
GFN-22's purpose was to find a world record prime, and that's no longer possible.
Apologies for the short notice, but... it will be back! (Hopefully. Also hopefully soon.)
