Roy Johnson,
I am sure once you get all the bugs worked out one of your solutions will be the winner (minus my Inline::C solution). Let me know when you think it is bug free and I will update. As it stands now, it breaks on 13316184461 (45863,290347). It says that 290347 is the answer, but that is larger than the sqrt().

Cheers - L~R
