Formula

E.g.f. satisfies: A(x/G(x)) = 1 + x where G(x) = Sum_{n>=0} ((1+x)^n-1)^n/n! and G(x) = x/Series_Reversion(A(x)-1) = e.g.f. of A192935.

Example

E.g.f.: A(x) = 1 + x + 2*x^2/2! + 18*x^3/3! + 324*x^4/4! + 8600*x^5/5! +...
where A(x/G(x)) = 1 + x and G(x) is the e.g.f. of A192935:
G(x) = 1 + x + 4*x^2/2! + 39*x^3/3! + 592*x^4/4! + 12965*x^5/5! +...
