OEIS Sequences

Triangle read by rows of Stirling numbers of first kind, s(n,k), n >= 1, 1 <= k <= n. A8275
Triangle of Stirling numbers of first kind, s(n,k), n >= 0, 0 <= k <= n. A48994
Unsigned Stirling numbers of first kind, s(n+1,2): a(n+1) = (n+1)*a(n) + n!. A254
Triangle of unsigned Stirling numbers of the first kind (see A048994), read by rows, T(n,k) for 0 <= k <= n. A132393
Triangle T(n,k), 0 <= k <= n, read by rows, giving coefficients of the polynomial (x+1)(x+2)...(x+n), expanded in increasing powers of x. T(n,k) is also the unsigned Stirling number |s(n+1, k+1)|, denoting the number of permutations on n+1 elements that contain exactly k+1 cycles. A130534
Triangle read by rows: T(n,k) = |s(n,n+1-k)|, where s(n,k) are the signed Stirling numbers of the first kind A008276 (1 <= k <= n; in other words, the unsigned Stirling numbers of the first kind in reverse order). A94638
Triangle of Stirling numbers of first kind, s(n, n-k+1), n >= 1, 1 <= k <= n. Also triangle T(n,k) giving coefficients in expansion of n!*binomial(x,n)/x in powers of x. A8276
Triangle related to the asymptotic expansion of E(x,m=3,n). A163932
Alfred Moessner's factorial triangle. A125714
a(n) = 12·n2. A135453
