Vaclav Kotesovec, Table of n, a(n) for n = 0..250
EXAMPLE
E.g.f.: A(x) = 1 + x + 3*x^2/2! + 17*x^3/3! + 86*x^4/4! + 674*x^5/5! +...
where
A(x) = 1 - log(1-x)/(1-x) + log(1-x)*log(1-x^2)/((1-x)*(1-x^2)) - log(1-x)*log(1-x^2)*log(1-x^3)/((1-x)*(1-x^2)*(1-x^3)) +...
PROG
(PARI) {a(n)=n!*polcoeff(1+sum(m=1, n, prod(k=1, m, -log(1-x^k +x*O(x^n))/(1-x^k) ) ), n)}
