OEIS Sequences

Number of integer partitions of n with no adjacent parts having quotient > 2. A342094

Number of unlabeled 3-connected graphs with n edges. A338511

Triangle read by rows: T(n,m) (n >= m >= 1) = number of line segments formed by drawing the lines connecting any two of the 2*(m+n) perimeter points of an m X n grid of squares. A331454

a(0) = 0 by convention; for n>0, a(n) is the number of edges in the n-th figure shown in A255011 (meaning the figure with 4n points on the perimeter). A331448

Alternate partial sums of binomial(3n,n)²/(2n+1). A188683

Antichain-Chain Quilt Numbers: Square table of the number of ASM quilts of type A₂(j) x C_k read down antidiagonals, where C_k is the chain poset or rank k and A₂(j) is the rank 2 poset with a unique minimal and maximal element and j atoms. A374822

Number of (w,x,y) with all terms in {0,...,n} and w ≠ x and x < range(w,x,y). A212970

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

Expansion of ∑_k>0 x^4·k/(1+x^k)⁵. A363618

Number of cells formed by connecting all the 4n points on the perimeter of an n X n square by straight lines; a(0) = 0 by convention. A255011
