OEIS Sequences

This table (read by rows) shows the coefficients of sum formulas of n-th subfactorial numbers (A000166). The n-th row (n>=1) contains T(i,n) for i=1 to n, where T(i,n) satisfies Subf(n) = ∑_i=1..n T(i,n) * n^n-i. A101559

T(n,k)=Number of nXk 0..4 arrays with every row and column nondecreasing rightwards and downwards, and the number of instances of each value within one of each other. A200990

Decimal representation of the x-axis, from the left edge to the origin, of the n-th stage of growth of the two-dimensional cellular automaton defined by "Rule 918", based on the 5-celled von Neumann neighborhood. A284409

Where the parity of A352931 changes. A352932

Numbers k such that the period of the continued fraction for sqrt(k) contains exactly 11 ones. A31779

Number of hierarchical orderings with at least 2 elements on each level for n unlabeled elements. Unlabeled analog of A097236. A109509

This sequence and A139143 are complements. a(1) = 1, A139143(1) = 2, a(n+1) = a(n) + ∑_{k = 1..n} A139143(k). A139142

T(n, k) = [x^k] ∑_j=0..n Pochhammer(x, j), for 0 <= k <= n, triangle read by rows. A326326

Number of n X 4 0..4 arrays with every row and column nondecreasing rightwards and downwards, and the number of instances of each value within one of each other. A200986

Number of nX6 0..4 arrays with every row and column nondecreasing rightwards and downwards, and the number of instances of each value within one of each other. A200988
