OK. I'll bite. Where did this formula come from?

Very nice link, Binbin. That is was exactly what I was trying to do, only they didn't include the math error I made in my calculations. :)

I was using the method to parameterize Pythagorean triples (a,b,c) in terms of s and t. Since we're looking at c^4 instead of c^2 (to make sure that c itself is a perfect square), I can see why the numbers got quite large. My solution for n=2 was for larger numbers than my n=3 solution, although even my n=1 solution had the magnitude of a as 10^16 and b was 10^21. I didn't find anything on the order of 10^13.

Interesting. I've solved several more puzzles in the Community group after this one, but I still can't see your solution, Binbin. It's obviously much smaller than mine is, which is why I'm interested in figuring out how you did this.

Great catch! Test case added; and by "some solutions" you mean "All solutions except yours and mine."
