• Numerators of continued fraction convergents to sqrt(887).at n=6A042714
• Number of compositions of n such that every restriction to a circular subinterval has a different sum.at n=40A325679
• a(n) = number of triangles with integer sides i <= j <= k with radius of circumcircle <= n.at n=32A331229
• 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.at n=40A392228
