As well as double 69 in the exponent!

Another impressive one from Ryan (#14 on the overall biggest list, and he also got #11, #12 spots in the last 2 weeks)

M23516089 has a 70.456-bit (22-digit) factor: 1619450690983460996873 (P-1,B1=1200000,B2=76800000)


This is almost frustrating, as it was TF'ed to 70bit. But I really like it because the B1 is almost perfect.

k= 2^2*1 175 411 *7 323 571

Well, I decided to run a PP1 curse on my old already factored exponent.
This is my first pp1 factor

P+1 found a factor in stage #2, B1=500000, B2=26500000.
UID: firejuggler/Maison, M8805827 has a factor: 4175293398605056163377 (P+1, B1=500000, B2=26500000)

Sadly, a composite
M23517601 has a 195.647-bit (59-digit) composite (P27+P33) factor: 78650091603029033018091227770166444001988216065464577593033 (P-1,B1=1200000,B2=79200000)
