Stage2 of P-1
 

Stage 1 in P-1 factoring is fairly is easy to implement.
but I have no idea how to do the stage 2.
Can someone explain the process. :(

check out the eliptical curve thread (hopefully my link works) They pretty much explained how p-1 works. As for how to RUN p-1 factoring, my understanding is that you need to run stage one first by changing the last integer in the number listed in the worktodo.ini. A '1' will mean p-1 is finished, and a '0' means that p-1 still needs to be run on the number.
