This brings back memories to me. Almost exactly 2 decades ago a related theorem, prime factorisation being in P, was proved by a couple of undergrads working with a professor in IIT Kanpur, India [1]. The story and the sensation it caused is still fresh in my memory because I had just begun my post-graduation studies in another IIT (IIT Bombay). There was sort of a festival atmosphere in the campus; with all sorts of seminars arranged, discussion groups and what not.
To this day I have not tried to understand the paper; just that it was hailed as one of the shortest and most elegant proofs.
