[b]QUEUED AS C196_146_83[/b]

C196_146_83 has survived substantial ECM: 30K curves @ B1=300M and another 20K curves @ B1=850M (this last courtesy of yoyo@Home). Originally designated a GNFS candidate, subsequent analysis suggests SNFS edges out GNFS, especially when poly searching time is added to the effort. Sieving should be performed using 15e on the -r side.

This would suggest a sieving range for Q of 30M-980M using a target number of relations = 930M.

I tend to oversieve, so please adjust the Q sieving range as appropriate. If no one wants to postprocess this composite, I will do so once my 32 Gb machine completes its current 33-bit efforts.
