OEIS Sequences

Triangle of Stirling numbers of the second kind, S2(n,k), n >= 1, 1 <= k <= n. A8277
Stirling numbers of second kind S(n,3). A392
Triangle read by rows: T(n,k) is the number of primitive (aperiodic) word structures of length n using exactly k different symbols. A137651
3rd level triangle related to Eulerian numbers and binomial transforms (A062253 is second level, triangle of Eulerian numbers is first level and triangle with Z(0,0)=1 and Z(n,k)=0 otherwise is 0th level). A62254
