OEIS Sequences

Number of graphs with a distinguished bipartite block, by number of vertices. A49312

Dirichlet g.f.: ∏_k>=2 (1 + k^-s)^{5^(k-1}). A344268

Triangle read by rows: T(n,k) is the number of deco polyominoes of height n and having k columns of even length (0 <= k < n). A deco polyomino is a directed column-convex polyomino in which the height, measured along the diagonal, is attained only in the last column. A121748

Partial sums of the number of active (ON, black) cells in n-th stage of growth of two-dimensional cellular automaton defined by "Rule 641", based on the 5-celled von Neumann neighborhood. A273311

Combinations of a partition: number of ways to label a partition (of size n) with numbers 1 to n. A78760

Consider the 2ⁿ⁺¹ polynomials f(x) with coefficients 0 or 1 and degree <= n. Sequence gives triangle read by rows, in which T(n,k) (n>=0) is the number of such polynomials of thickness k (0 <= k <= n+1). A169945
