%N Number of partitions of 3*n^3 into parts that are at most n.

%H Vaclav Kotesovec, <a href="/A258303/b258303.txt">Table of n, a(n) for n = 0..100</a>

%F a(n) ~ exp(2*n + 1/12) * 3^(n-1) * n^(n-3) / (2*Pi).

%p T:=proc(n,k) option remember; `if`(n=0 or k=1, 1, T(n,k-1) + `if`(n<k, 0, T(n-k,k))) end proc: seq(T(3*n^3, n), n=0..20);
