Mersenne: M727 has a factor?!?!?

Hi!! Tell me I'm wrong... and if not, what happened?? I just made a slight error in adding a P-1 factor assignment to the WORKTODO.INI file for M727 and came up with the following result (on screen): P-1 on P727 with B1=30, B2=1 P727 stage 1 complete. 116 transforms. Time: 0.018 sec.

P-1 on P727 with B1=30, B2=1 P727 stage 1 complete. 116 transforms. Time: 0.018 sec. (4659194 clocks) Stage 1 GCD complete. Time: 0.001 sec. (164887 clocks) P727 has a factor: 11633 This meets all the criteria too 1) 11633 is PRIME. 2) 2kp+1 = 2*(8)*727+1 = 11633
