Number of unrooted non-binary leaf-multi-labeled trees with n leaves on the label set [2].
The reference has a mistake in formula 4.3. Rather than "k*g(n-1,k) + g(n,k) + Sum_{j=1..n-1} g(j,k)*g(n-j,k)" it should be "k*g(n-1,k) + g(n,k) - Sum_{j=1..n-1} g(j,k)*g(n-j,k)". Table 4.3 (A220832, this sequence, A220834, A220835) is consequently also incorrect.
