# Should I ask this question on stackoverflow or math.stackexchange?

I am working on Project Euler Problem 420. My solution has alot of code, and I've asked questions about the math involved on math.stackexchange. However, My code is still not producing correct results, and I'm not sure if it is a code bug, or a math problem. Should I ask for help on math.stackexchange, or stackoverflow, or both?

Update: The question was asked at math.SE (Project Euler $420$) and has since been voted closed (although there is a vote for it to be re-opened).
