OEIS Sequences

Column 0 of square array A211970 (in which column 1 is A000041). A211971

a(1)=5, a(2)=2, a(n) = 5·a(n-1) + 2·a(n-2). A189746

E.g.f.: A(x,y) = exp(-1-y) * ∑_n>=0 (exp(n·x) + y)ⁿ / n!, where A(x,y) = ∑_n>=0 xⁿ/n! * ∑_k=0..n T(n,k)*y^k, as a triangle of coefficients T(n,k) read by rows. A326600

G.f. satisfies A(x) = 1 + x·A(x)⁴*(1 + x·A(x)²). A365181

Triangle read by rows: T(n,k) is the number of digraphs on n labeled nodes with k arcs and a global source and sink, n >= 1, k = 0..max(1,n-1)*(n-2)+1. A350791

Position of sqrt(n) in the mapping N2QuQR1 given in A065936. A65938

Decimal representation of the diagonal from the corner to the origin of the n-th stage of growth of the two-dimensional cellular automaton defined by "Rule 302", based on the 5-celled von Neumann neighborhood. A287541

a(n) = sum of 2^k-1 such that floor(n/prime(k)) is odd. A371906
