OEIS Sequences

G.f.: ∑_n>=1 moebius(n)*xⁿ/(1 - Lucas(n)*xⁿ + (-1)ⁿ*x^2·n), where Lucas(n) = A000204(n). A204291

Triangle read by rows: T(n,m) (n >= m >= 1) = number of regions (or cells) formed by drawing the line segments connecting any two of the 2*(m+n) perimeter points of an m X n grid of squares. A331452

Triangular array giving number of labeled graphs on n unisolated nodes and k=0...n*(n-1)/2 edges. A54548

T(n,k) = count of degree k monomials in the power sum symmetric polynomials p(μ,k) summed over all partitions μ of n. A209664

Triangle read by rows: T(n,k) is the number of chiral pairs of colorings of the facets of a regular n-dimensional orthotope using exactly k colors. Row n has 2n columns. A325010

Number of partitions of n into 4 sorts of parts. A246936

Number of hill-free Dyck paths of semilength n+2 and having length of first descent equal to 2 (a hill in a Dyck path is a peak at level 1). A118973

Table read by antidiagonals: Place k equally spaced points on each side of a regular n-gon and join every pair of these n·k points by a chord; T(n,k) (n >= 3, k >= 0) gives the number of regions in the resulting planar graph. A367304

Triangle read by rows: T(n,k) is the number of hill-free Dyck paths of semilength n and having length of first descent equal to k (1<=k<=n; n>=1). A hill in a Dyck path is a peak at level 1. A118972

Number of distinct sums <= 1 of distinct reciprocals of integers <= n. A212607
