[B]QUEUED AS 7p5_302 on 15e_small[/B]

SNFS-255.22 C202 HCN (7+5,302), ECM to t56. I think this fits 15e small, but I'll let you decide.

I also test sieved on the rational side, that's slightly slower.

It could have been done as a GNFS job, but poly selection would probably take longer than it would save on sieving.

I'll do the LA.

That poly is pretty bad, about 20% worse than the record score for that size and the skew is rather large. Can I improve the poly overnight and post a new job request for it tomorrow?
