OEIS Sequences

Irregular triangle: p(k, x) = 2·x*p(k-1, x) + (1 - x²)*p(k-2, x) for even k, p(k, x) = 2*(k-1)*p(k-1, x) - x·p(k-2, x) for odd k. A123242

Expansion of ∏_n>=1 (1 - x^3·n)/(1 - xⁿ)³ in powers of x. A273845

The number of vertices on a nonagon formed by the straight line segments mutually connecting all vertices and all points that divide the sides into n equal parts. A332428

Numbers n such that n¹+n+1, n²+n+1, n³+n+1 and n⁴+n+1 are all prime. A219117

a(n) is the number of regions formed by n-secting the angles of a nonagon (enneagon). A335781

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

G.f.: ∑_n>=0 xⁿ * (1 + xⁿ)ⁿ / (1 - xⁿ⁺¹)ⁿ⁺¹. A325046

Number of edges in a hexagon when n internal hexagons are drawn between the 6n points that divide each side into n+1 equal parts. A357198

Number of 3-regular cubic partitions of n. A335602
