You have a typo in the title of this post, and in the pastebin file.This is actually the factorisation of 13691^61-1, not 13601....

Yes, you are correct. I spotted it right after I posted the poly in the other thread. I reviewed everything at that time and saw it was a typo in the comment of the poly which carried into the description. All the math/poly was correct so I just let it go through.

I forgot all about it until you caught me. Nice detective work... :smile:
