I would like to reserve the following numbers for ECM to t50:

C275_150_116
C189_137_47
C191_138_62
C203_137_127

Thanks.

With the noted exceptions, these have survived 7600 curves @B1=43M with no factors found. Releasing.

Nice quick hit.

The above numbers have been factored or run to 7600 curves @B1=43M with no factor found. Releasing.

ECM is still running on the other two composites C191_138_62 and C203_137_127.

I'd like to reserve the following for ECM to the t50 level:

C267_144_142
C270_150_98
C282_148_141
C244_147_47
C173_139_59
C160_146_39
C162_148_35

Thanks.

Ran 7600 curves @B1=43M on both of these with no factors found. Releasing both numbers.

With the noted exception, all of the above have survived ECM for 7600 curves @B1=43M with no factors found. Releasing numbers.

C197_115_104 (t55)
 

I would like to reserve this composite for ECM to the t55 level. It will take a few weeks.

Thanks
