%N Number of integer-sided triangles with sides a,b,c, a<b<c, a+b+c=n that are right triangles.
%C Also number of right integer triangles with perimeter n having integral inradius. - _Reinhard Zumkeller_, May 05 2002
%C Every integer-sided right triangle has integer inradius. If the triple is [p^2-q^2,2pq,p^2+q^2] then inradius = pq-q^2. - _Michael Somos_, Sep 13 2005
