    Formulas for generating Pythagorean triples - Wikipedia, the free encyclopedia
    Sure all 12 ways might not apply... but it's a start. Hint: Take a look at number 10 (X).

    Well that's usually how it works when you don't want to use the brute force method. I don't see what's hard about X (10).
