• a(n) = floor(n*phi^16), where phi is the golden ratio, A001622.at n=18A004931
• Take an n X n square grid of points in the plane; a(n) = number of ways to divide the points into two sets using a straight line.at n=18A114043
• p-INVERT of the positive integers, where p(S) = (1 - S)^2.at n=9A290917
• p-INVERT of (0,1,0,1,0,1,...), where p(S) = 1 - S - S^2 + S^3.at n=19A291241
• Table read by antidiagonals: Place k equally spaced points on each side of a regular n-gon and join every pair of these n*k points by a chord; T(n,k) (n >= 3, k >= 0) gives the number of edges in the resulting planar graph.at n=40A367305
