OEIS Sequences

Consider the e.g.f. A(x,y) = ∑_n>=0 ∑_k=0..n T(n,k) * x^2·n-2·k+1 * y^2·k / (2·n+1)! and related functions B(x,y) and C(x,y), as defined in the Formula section. Sequence gives the triangular array of coefficients T(n,k) (n>=0, 0<=k<=n) of A(x,y). A326797

Number of rooted cubic maps with 2n nodes and a distinguished Hamiltonian cycle: (2n)!(2n+1)! / (n!²*(n+1)!(n+2)!). A356

Coefficient of x⁸ in expansion of (1+x+x²)ⁿ. A5716

Triangle T(n,k) read by rows: related to David G. Cantor's σ function. A73165

Sum of divisors of those numbers n such that n and n+1 have the same sum of divisors. A53215

Square array T(n,k) read by antidiagonals: T(n,k) = ∏_1<=i<=j<=k (n+i+j-1)/(i+j-1). A102539

a(n) = 26·n². A244633

Form array in which n-th row is obtained by expanding (1 + x + x²)ⁿ and taking the 4th column from the center. A14533

Triangular array, read by rows, associated with sums of certain Vandermonde determinants. A133112
