# Knots and Pythagorean Triangles

There are equally spaced $$12$$ knots in the loop of string in Figure-1. This string loop can be transformed into Figure-2, which is a right triangle with a knot on each of its vertices.

Does this same transformation work for any other number of knots $$k\neq12$$?

Find the minimum $$k>12$$.
If there is no such $$k>12$$, enter 0.
