C224_147_40 and C202_149_37 are the only y<=40 numbers still without t50.

Reserving C267_144_142 with the intent of doing the SNFS (about 120 million CPU-seconds) after 5000@6e8 ECM: how much ECM has this had already?

Only 4600@43M. A really good poly there: C267_144_142 = (71²⁴)⁶ + 144*(2⁷⁰*3⁴⁷)⁶ :-)

I ran a full t50 on it. But that's a drop in the bucket compared to the ECM effort you're planning.

A typo there, 7600 of course!

Both survived 7600 curves @B1=43e6 with no factors found. Releasing.

C267_144_142 survived 4992@6e8 and is now sieving. On 40 threads it'll probably take March plus a bit of April.

C203_148_46
C229_150_58

Both numbers survived 7600 curves @B1=43M with no factors found. Releasing both. Thanks.
