If you mean another one, please let me know.

No, just a duplicate reservation. Sorry.

My current ECM reservations are nearing completion, alas with no factors found. But they're not quite done, maybe something will hit...

I would like to reserve C178_149_35 and C286_149_93 for ECM to the t50 level. Thanks.

I got this hit with ECM using B1=43M and sigma=2514770810.

Code:

prp51 = 199977812975015804656613653207154004137892731722369

Results also in fdb.

C200_143_34
C184_146_89

All four of these withstood 7600 curves @B1=43M with no factors found. Releasing.

Lastly, C232_143_46 survived t50 (with no factors found) and now I'm taking it upwards to t55.

Reserving C177_131_83 for ECM to t55.

swellman · 2015-04-08, 14:39

C286_149_93 survived 7600 curves @B1=43M with no factors found. Releasing.

swellman · 2015-04-09, 11:33

Reserving C186_145_72 and C237_141_52 for ECM up to t50.

swellman · 2015-04-14, 11:06

C178_149_35 survived 7600 curves @B1=43M with no factors found. Releasing.

C232_143_46 survived the same plus 10k curves @B1=110M. Please transfer this number to Ryan for SNFS.

Lastly, I would like to reserve C180_146_44 for ECM to t50. Thanks.
