A331226

a(n) is the number of triangles with integer sides i <= j <= k with squared radius of circumscribed circle b(n) = A331224(n)/A331225(n). Records of numbers of distinct triangles such that all smaller radii produce fewer triangles sharing the same radius of circumcircle than the current radius b(n).
