UID: storm5510/7700_Kaby_Lake, M7755521 has a factor: 105137409539055148931876353 (P1, B1=370000, B2=8140000, E=6)
86.442 bits. This is not a record here, or for me. However, it is the first I have found of any significance is a really long time.

I shortened these a little for readability.

297034017173995954820063 77 bits The exponent has previously had a total about 60% of a first time check run (3 different users). What a waste of cycles when a factor was so close. I have done 7 different single bit factoring runs on this exponent (2009, 2012, 2014, 2014, 2015, 2017, 2020)

If the exponent would have received proper P1'ing with stage 2, the same factor would long have been found, even barely with the lower GPU72 bounds.

Does this make it simpler? Now with sortable columns for exponent/bits/date.
