Numerators of continued fraction convergents to sqrt(887). A42714

a(n) = number of triangles with integer sides i <= j <= k with radius of circumcircle <= n. A331229

Array read by antidiagonals: Place k points in general position on each side of a regular n-gon and join every pair of the k·n boundary points by a chord; T(n,k) (n >= 3, k >= 0) gives the number of regions in the resulting planar graph. A392228
