Poly selection was done by Lots of us
Postprocessing will be done by mdettweiler We have almost enough relations....check the end of the thread for any more sieving needed before starting any ranges! See next message for relation upload instructions. Poly: Code:

Was that a complete search with GGNFS?
Here's a nice one that popped out of msieve, searching around the higher than default leading coefficient (to not potentially waste effort). It has a smaller 'e' value but sieves ~4% faster. Code:
# norm 2.230278e13 alpha 6.709216 e 2.485e11 skew: 508389.51 c0: 1715096044102766131555640234382300 c1: 72526691734251272118367460690 c2: 120771683611520445554704 c3: 483822867366235288 c4: 398591914077 c5: 876240 Y0: 198414717006063417277428937 Y1: 3937215344981633 Code:

This one might be slightly better (assuming that the "combined" value from msieve is the same as the "e" value): Code:
R0: 667075514232026401037903971 R1: 1036651090752913 A0: 70301050564161042395853180825579264 A1: 760641393409756411433308787652 A2: 456862733931472272483861 A3: 400760058780476342 A4: 26481981572 A5: 2040 skew 3879684.27, size 2.230540e013, alpha 7.209819, combined = 2.495775e011

Which siever did you use? And shouldn't alim and rlim be higher than 9M? (They were 12M for the C136.)

That was ~12 hours of searching. The "c5" value being searched when I stopped it was >1,500,000, so it had been a while since it had found that poly....
