I found a very easy one (randomly selected a nice number and spent <1 GhzD effort) in M3331331 yesterday, but the number was factored previously: mersenne.ca, Primenet Details. What bothers me is that the same PRP residue is identical for the PRP test with 1 factor and the PRP test with 2 factors? This is a bug, isn't it?

The factor I'm most proud of is this lucky 118bit one in M70553939 which I found in normal LL/PRP testing.
