I have completed my double-check of bases 60, 61, 62, 63, 64, 65, 66, 67, 68, and 70 to n=100000.

Note that the limits for 63, 64, and 70 were below n=100000.

87384*70^87384+1 is the only new prime found.

I will take Cullen base 60 from n=100,000 to 1.5M.

Base 11 for Cullen and Woodall is still sieving; I would like to also take base 127 for both, additionally for a (at least partial) double check.

Ryan, have you had a sieve file for your base 11 run?

I have a sieve file for Woodall base 11. Will send it to you in a private message.
