OEIS Sequences

Define E(n) = ∑_{k >= 0} (-1)^floor(k/3)*kⁿ/k! for n = 0,1,2,... . Then E(n) is an integral linear combination of E(0), E(1) and E(2). This sequence lists the coefficients of E(0). A143628

Expansion of 1/(1+2·x*c(x)), c(x) the g.f. of Catalan numbers A000108. A126984

Triangle of 3-restricted Stirling numbers of the first kind (T(n,k), 0 <= k <= n), read by rows. A144633

a(n) = binomial(2·n, n)² / (1-2·n). A10370

G.f.: q-Cosh(x,q)² - q-Sinh(x,q)² at q=-x. A198199

Triangle read by rows: T(n,k) is the coefficient of x^k (0<=k<=n) in the monic characteristic polynomial of the n X n matrix with 3's on the diagonal and 1's elsewhere (n>=1). Row 0 consists of the single term 1. A103247

a(n) = 1 + ∑_k=2..n (-1)^k * k² * a(floor(n/k)). A361983
