M5210099 has a factor: 2944892728119316210127 (P1, B1=2500000, B2=207500000) (71.319 bits)
It's puny, I know, but I'm fond of it because it's my first nonECM stage 2 Mersenne factor. My previous P1 and P+1 factors were both found in stage 1. Last fiddled with by Happy5214 on 20210813 at 19:51 Reason: Adding size
