OEIS Sequences

The number of edges on a nonagon formed by the straight line segments mutually connecting all vertices and all points that divide the sides into n equal parts. A332429

L.g.f.: ∑_n>=1 [ ∑_k>=1 k^2·n * x^k ]ⁿ / n. A276754

The array described in A059513 read by antidiagonals in the 'up' direction. A59574

Table read by antidiagonals: Place k equally spaced points on each side of a regular n-gon and join every pair of the n*(k+1) boundary points by a chord; T(n,k) (n >= 3, k >= 0) gives the number of edges in the resulting planar graph. A367324

Square roots of partial sums of A386369 that are square numbers. A386370

The array described in A059513 read by antidiagonals in the direction of construction. A59575
