E.g.f. A(x) satisfies: A(A(x)) = x·A'(x) with A(0)=0, A'(0)=1. A179420

Place n equally spaced points on each side of an equilateral triangle, and join each of these points by a chord to the 2·n new points on the other two sides: sequence gives number of edges in the resulting planar graph. A366485

a(n) = ∑_k=0..n k·A000009(k). A270105

E.g.f. A(x) satisfies: x·A(x) equals column 0 in the matrix log of the Riordan array (A(x), x·A(x)). A179421

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. A367305
