Hmmm. I've used this particular machine many times, and have since built another matrix for 11_236_plus_10_236 with no issue. But I can't argue with your success.

Unconnected, do you mind finishing the postprocessing for GC_12_230? I won't have another capable machine to finish LA on this number until late April.

Thanks for the feedback - was driving me crazy!

Does the C219 from 145^66+66^145 sieved on 15e have enough relations? I can't start that job for a couple more weeks but it appears to fall short of the usual 410-450M relations seen with a 32-bit job. Just asking. If the count is as intended I will be happy to work it until a matrix builds.

ramshanker, Andrey: most Cxxx_yyy_zzz numbers sieved by NFS@Home's 14e are indeed x^y+y^x numbers, but I also use the same naming convention for Aliquot composites, with the middle part being the sequence starting point and the last part being the index

Sean: yeah, I too noticed that it seemed to fall short of the usual number of relations for a 32-bit LPs task. However, 15e and 32-bit LPs are outside of my area of expertise, so I left that number alone.
