Andrew Howroyd, Table of n, a(n) for n = 0..50
FORMULA
E.g.f.: B(A(x)) where A(x) = log(Sum_{k=1..n} 2^(n^2)x^n/n!) and B(x)= x*exp(x).
a(n) = Sum_{k=1..n} k*A186236(n,k).
MATHEMATICA
a=Sum[2^(n^2)x^n/n!, {n, 0, 20}]; Range[0, 20]! CoefficientList[Series[a Log[a], {x, 0, 20}], x]
PROG
(PARI) seq(n)={my(g=log(sum(k=0, n, 2^(k^2)*x^k/k!) + O(x*x^n))); Vec(serlaplace(g*exp(g)), -(n+1))} \\ Andrew Howroyd, Nov 07 2019
