Alois P. Heinz, Table of n, a(n) for n = 0..50

Formula

a(n) ~ sqrt(6*Pi) * (6^5/5!)^n * n^(6*n+1/2) / (8 * exp(6*n) * (log(2))^(6*n+1)). - Vaclav Kotesovec, Mar 23 2016

Mathematica

With[{r = 6}, Flatten[{1, Table[Sum[Sum[(-1)^i*Binomial[j, i]*Binomial[j - i, r]^k, {i, 0, j}], {j, 0, k*r}], {k, 1, 12}]}]] (* Vaclav Kotesovec, Mar 22 2016 *)
