%N Expansion of g.f. exp(Sum_{n>=1} A061163(n)*t^n/n).
%F O.g.f.(t) = g satisfies the algebraic equation of order 30 in the form: 1 + Sum_{n=1..30} p(n,t)*g^n = 0, where p(n,t) are polynomials of t of order n with integer coefficients. For example p(15,t) = 2*t^9*(77558760*t^6 - 1112153600*t^5 - 2309989894*t^4 + 784164428*t^3 + 6287761*t^2 - 9848*t + 3)
