FORMULA
E.g.f. A(x) satisfies: A'(x) = A(A(x) - 1)^2. - Paul D. Hanna, Nov 25 2014 [corrected by Paul D. Hanna, Sep 07 2024]
EXAMPLE
E.g.f.: A(x) = 1 + x + 2*x^2/2! + 10*x^3/3! + 88*x^4/4! + 1152*x^5/5! + ...
PROG
(PARI) {a(n) = my(A=1+x+x*O(x^n)); for(i=0, n, A = 1 + serreverse(intformal(1/A^2))); n!*polcoef(A, n)}
