PRP on OBD candidates

Currently, it would be premature to attempt a PRP on a gigadigit Mersenne number with prime exponent.

Only one has been taken in TF to 91 bits, none to 92 bits, and none have been P-1 factored to...

Ram required versus exponent for P-1 stage 2 in Mlucas

Stage 1 can be run to gigadigit or higher on 12 GiB ram, probably less ram.

Stage 2 is much more demanding of ram than stage 1.
A rough estimate of stage 2 ram required for successful launch is...
