Congratulations for the factorization. The root property of the polynomial is pretty good. Do you still have the raw polynomial (say before size/root optimization)?

Thanks Bruce. I think it is still remaining (but better ask Sam). There are some smaller (in terms of size) composites e.g. N226 c177, N240 c186. Sam will do the c186 and Bill&me are about to start...
