One interesting thing I saw at the APL Moot - Jane Sullivan showed me the open-source YAFU - Yet Another Factorization Utility - http://yafu.sourceforge.net/ . It had great performance. I forget the example she showed me - a 100-digit number? - but " q: " ran for many hours and did not come up with the factors.
I've thought it would be a good project to learn how to update the J source.
