Table of n, a(n) for n=0..14.

Formula

Let G(x) be the g.f. of A277042, then g.f. A(x) satisfies:

(1) G(x*A(x)) = (1+x)*A(x).

(2) A(x/(G(x) - x)) = G(x) - x.

(3) A(x) = (1/x)*Series_Reversion(x/(G(x) - x)).

(4) G(x) = x + x/Series_Reversion(x*A(x)).

Example

G.f.: A(x) = 1 + x^3 + 30*x^6 + 10921*x^9 + 6308995*x^12 +...
such that the binomial transform forms the g.f. of A277041:
A(x/(1-x))/(1-x) = 1 + x + x^2 + 2*x^3 + 5*x^4 + 11*x^5 + 51*x^6 + 246*x^7 + 897*x^8 + 13526*x^9 + 115631*x^10 + 614681*x^11 + 8739556*x^12 + 89877217*x^13 + 596072842*x^14 +...+ A277041(n)*x^n +...
Also, A(x/(G(x) - x)) = G(x) - x where G(x) = g.f. of A277042 where
G(x) = 1 + x + x^3 + 27*x^6 + 10666*x^9 + 6174792*x^12 +...+ A277042(n)*x^n +...
