COMMENTS
A solution is primitive if it cannot be obtained multiplying another solution by a square greater than 1, i.e., if GCD(x,y,z) is squarefree.
The first two solutions are reported in Choudhry's paper, whose main purpose is providing a parametric solution.

EXAMPLE
108 + 124 + 129 = 19^2, 108^2 + 124^2 + 129^2 = 209^2, 108^3 + 124^3 + 129^3 = 2305^2.
