OEIS Sequences

Square array A(n,k), n>=0, k>=0, read by antidiagonals, where A(0,k) = 1 and A(n,k) = ∑_j=0..n-1 k^j * binomial(n-1,j) * A(j,k) for n > 0. A306245

G.f. A(x) satisfies A(x) = 1 + x·A(3·x / (1 - x)) / (1 - x). A355081

Expansion of (theta₃(z)*theta₃(11z) + theta₂(z)*theta₂(11z))⁴. A28612

Triangle read by rows: T(n,k) is number of Dyck paths of semilength n having k ascents of length 3 (0<=k<=floor(n/3)). Also number of ordered trees with n edges that have k vertices of outdegree 3. A114506

Numbers k such that σ(k) = ψ(k) + φ(k) + ω(k)⁵. A391448

G.f.: A(x) = INV(x*(1-x) - x²*INV(x*(1-x)² - x²*INV(x*(1-x)³ - x²*INV(x*(1-x)⁴ - x²*INV(x*(1-x)⁵ - ...))))), where INV(F(x)) = series reversion of F(x). A196708
