OEIS Sequences

Number of vertices in the hyperoctahedral (or cocktail party) graph of order n. A368756

The number of vertices on an octagon formed by the straight line segments mutually connecting all vertices and all points that divide the sides into n equal parts. A333109

G.f.: ∑_k>=0 x^k * ∏_j=1..2·k (1 + x^j)/(1 - x^j). A385088

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 vertices in the resulting planar graph. A367322

Smallest number m such that A247462(m) = n. A247468

a(n) = (1/24)*n*((4·n + 3)*(2·n² + 1) - 3*(-1)ⁿ). A325656

Values of g-hat₄(n), a sum involving Stirling numbers of the first kind. A261689

Least b > 1 such that (b^prime(n²) - 1)/(b^prime(n) - 1) is prime. A353101

Expansion of 1/((1-x)(1-x⁷)(1-x⁹)(1-x¹⁰)). A29121
