Slight cross up here. I think Speedy first reserved it 3 pages ago

As long as nobody has previously asked for C217_67411_47 & It's not going to run for hundreds of hours on a 5960 X with 16 gig of RAM I also use for other things so it would probably need to fit in 9 gig tops I would be interested in taking. Thanks

Sorry about the mixup if you would like the credit I can email Greg

No need, it's fine, you reserved it first.

419M unique relations netted 337M unique. Filtering with TD set to 130 produced a 19.38M matrix, which took roughly 230hr to solve on half a 6-core i7-5820 (6 threads msieve, 5-6 other tasks).
