OEIS Sequences

Expansion of g.f. A(x) satisfying a(n) = [x^n-1] A(x)ⁿ⁺¹ for n >= 1. A361048

a(n) = ∑_0<=j<=i<=n A027113(i, n+j). A27130

a(n) is the number of 3 X 3 matrices with elements 1..n where at least one row is strictly increasing. A390904

G.f. satisfies: A(x) = (1/x)*Series_Reversion( x/(1 + x·A(x)² + x²*A(x)*A'(x)) ). A361049

a(n) = s(1)t(n) + s(2)t(n-1) + ... + s(k)t(n-k+1), where k = [ n/2 ], s = A023532, t = A001950 (upper Wythoff sequence). A25074
