Odd perfect related road blocks II - Page 50

wblipp · 2011-04-21, 03:46

Thanks to a flurry of factoring by Carlos Pinho and an unnamed person, all the p^11-1 less than 160 digits difficulty from all the txxx files except for the two newcomers are now factored.

This was supposed to be the post where I announced all had been factored. Unfortunately, the txxx files are dynamic - factoring a first composite in a low file will often result in new first composites in the higher files. Since the time I started the ECM prep work on these, two additional ones have slipped into the lists (343230305345881 and 1020392150510893).

This batch also contains factors for one additional number from Rich Dickerson, who has been helping with ECM prep work.

Two that are Brent composites and also Mishima Hisanori cyclotomic numbers and also Zeta-flux's "need two 12 digit factors."
