OEIS Sequences

a(n) = (n⁵ - 5·n⁴ + 5·n³ + 5·n² + 114·n + 120)/120. A161701

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

Imaginary Rabbits: imaginary part of a(0)=i; a(1)=-i; a(n) = a(n-1) + i·a(n-2), with i = sqrt(-1). A14291

Numbers k such that 225·2^k+1 is prime. A32489

a(n) = (8 - 2·n + 11·n² - 6·n³ + n⁴)/4. A289121

Number of partitions of n into square parts. A179662

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

Number of 3-element intersecting families (with not necessarily distinct sets) of an n-element set. A53155
