But I didn't make up those bounds. Before Tha found that factor the mersenne.org report would have said no-factor-to=66, and P-1 bounds (like this). Unfortunately the mersenne.org report suppresses the no-factor-to and max-p1-bounds data if a factor is known. Nothing shows up on the report because mersenne.org doesn't have a specific record of who did the P-1 and when, just what bounds it was done to. The oldest P-1 run I have on file is for M18,752,249 from 03-Jan-2000, so presumably a 12M exponent would have had its P-1 done several months/years earlier than that, and no records of who-did-what-when were kept at the time (or were kept and have since been lost).
