R745
 

I should apologise, I have not checked in with a status update for some time, and I notice today that my reservation on R745 has been removed.

I'm still working on this (and hence would like to re-reserve), heading up to 300k on all remaining k-values. News for today is that we have a new prime, k=11138 has been eliminated.
