Hello,
Please extend f38_158p1 sieving range to 130M. I miscalculated how far I would need to sieve and it's not going to get enough relations by 110M. Chris

I just enqueued 9p8_305, the last of the Homogeneous Cunningham composites suitable for 15e_small.
There will be no more. All further HCN work will need to sieve on 15e or f_small. Last fiddled with by swellman on 20201002 at 12:27

f57_142p1 is on the wrong queue.
Hello,
Sorry for the abiguity in my post, I meant sieve f57_142p1 with the 15e siever, but on the 15e_small queue. Can you move it from the 15e queue to 15e_small (it's not started sieving yet so could be killed and a new job started). Chris
