PLEASE NOTE. a = √2n-1) b = n-1 c = n One thing I always wonder about the pythagorean theorem, is about triplets like 5,12,13; where c-b is 1. That's why I created this: A calculator to calculate such triplets. Look for matching indexes of each list; any index that has a number in the "sequence column" is one of these, showing the c and a of it, and b = c - 1. This was fascinating with some mathematical research.
