Reached my laptop memory limit of 16GB. I'll have to release it once again. Jon, maybe add more sieving although I managed to pass the filtering stage with td set to 110. Check attachment.

I'll take C187_138_106 next.

45.4 hours on 7 cores E5-2650v2 for 9.34M matrix at density=160. Log attached and at http://pastebin.com/qRF71imQ

Taking P223 (284688...)+1(14e).

This is going to be a big job; 26.40M matrix, which is much larger than you'd expect for a sextic SNFS number with log(N)~229.87.

Ah, the polynomial p^31+p-2 is (p-1) (polcyclo(31)(p)+1)
