Amphoria found a good poly, repeated here for reference. Hoping for something within the msieve expected range for e of 1.37e-014 to 1.58e-014. Thanks for any assistance folks can lend.

Bump. Can anyone lends some cycles?

I have 2.5 thread-years queued up on this job starting probably tomorrow and aiming to finish by Christmas; I don't think we need much more?

@unconnected
What is the GNFS poly currently used for Aliquot 842592:i8053?
https://escatter11.fullerton.edu/nfs/crunching_e.php
Promise to find a better one.

Is E-score calculated by cado the same as that msieve calculates? My poly for this number at 2.82e-13 is the best score found for a C172 on this forum; yours would beat any poly found for a C171 (never mind a 172).
The latest CADO may have caught msieve for poly select- particularly for those who don't have a GPU setup.
