Appears in sequences

• E.g.f.: 1/(1-x*exp(x)).at n=8A006153
• Triangle of functions in a size n set for which the sequence of composition powers starts with a length k stem (index) before entering a cycle (period).at n=23A225540
• Square array T(n,k), n >= 0, k >= 1, read by antidiagonals, where column k is the expansion of e.g.f. 1/(1 - x^k * exp(x) / k!).at n=44A351703
• Square array T(n,k), n >= 0, k >= 0, read by antidiagonals downwards, where T(n,k) = n! * Sum_{j=0..n} k^(n-j) * (n-j)^j/j!.at n=53A351761
• Square array T(n,k), n >= 0, k >= 0, read by antidiagonals downwards, where T(n,k) = n! * Sum_{j=0..n} (k * (n-j))^j/j!.at n=53A351790
• Array read by ascending antidiagonals: A(n,k) = n! * [x^n] 1/(1 - x*exp(x))^k.at n=46A380841
