%N Ordered long legs of primitive Pythagorean triangles.
%C Consider primitive Pythagorean triangles (A^2 + B^2 = C^2, (A, B) = 1, A < B); sequence gives values of B, sorted.
%C Any term in this sequence is given by f(m,n) = 2*m*n or g(m,n) = m^2 - n^2 where m and n are any two positive integers, m > 1, n < m, the greatest common divisor of m and n is 1, m and n are not both odd; e.g., f(m,n) = f(2,1) = 2*2*1 = 4. - _Agola Kisira Odero_, Apr 29 2016
%C All terms are composite. - _Thomas Ordowski_, Mar 12 2017
