9000@11e7 and 1200@26e7 with no factors - I think it's ready for GNFS.

C172 @ i2152
 

Here is a baseline to beat ... and continuing.

A better poly for c172 @i2152 ?
 

Hold on. I hope it's not too late.

This one is slightly faster - 70 days 10h 53m 28s
Let's queue it to NFS@Home.

Now c169 @ i2156 and it's ready for GNFS (resists almost full t55).
BTW, previous c173 blocker @ i2154 was cracked by ECM (P52 after ~4000@11e7).
