Hi, Could someone possibly send me the prime form algorithm supplied by a student, posted here a few days ago. It was part of his thesis. I have inadvertently deleted the post; but I ran it before I was so foolish, and it was FAST, and worked without the CM image. Hurrah for the 4096-algorithm. I would appreciate this very much. Peter PS--is there an archive of postings to this list? I couldn't find it.
