OEIS Sequences

Expansion of e.g.f. exp(-x)/(1-2·x). A354

Square array A(n,k), n >= 0, k >= 0, read by antidiagonals, where column k is the expansion of the e.g.f. exp(-x)/(1 - k·x). A320032

Triangle read by rows: T(n, k) = n! * 2^k * hypergeom([-k], [-n], -1/2). A374427

Numerators of convergents to 1 + 2/(3 + 4/(5 + 6/(7 + ...))). A113012

Form the difference table of the sequence {2^k*k!}, then divide k-th column entries by 2^k*k!. Array read by ascending antidiagonals, T(n, k) for n, k >= 0. A143410

Square array T(n,k) (row n, column k) read by antidiagonals defined by: T(n,k) is the permanent of the n X n matrix with 1 on the diagonal and k elsewhere; T(0,k)=1. A90628

Double subfactorials: a(n) = (-1)^floor(n/2) * n!! * ∑_{i=0..floor(n/2)} (-1)ⁱ/(n-2·i)!!. A334578

Triangle read by rows: T(n,k) is the number of symmetries of the n-dimensional hypercube that fix exactly 2·k facets; n,k >= 0. A342381
