A331043 - cp's OEIS frontend

A331043 a(n) is the number of triangles with integer sides i <= j <= k with squared radius of incircle b(n) = A331040(n)/A331041(n). Records of numbers of distinct triangles such that all smaller radii produce fewer triangles sharing the same radius of incircle than the current radius b(n).
