a(n) = ∑_k=1..n k! * k^n-3 * |Stirling1(n,k)|. A373870

Total number of vertices in the graph (see A392172) formed when n points are placed in general position on each edge of a square and a chord is drawn from each point to the 3·n points on the other three sides. A392173

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 vertices in the resulting planar graph. A392261
