Survived 7600 curves @B1=43M with no factors found. Releasing number.

C188_149_78
 

Reserving C188_149_78 for ECM to t50, and if necessary t55.

Test sieving suggests this may be a GNFS candidate, but I'm hoping it falls to ECM.

On C175_131_96, I have done 12927 curves at B1=110e6 and 5685 at B1=260e6 with no factors found.

I've also run 1000 hours of polynomial selection and will now proceed to personal-GNFS.
