OEIS Sequences

Generalized Stirling numbers, [n+6,6]_5. A1721

Generalized Stirling number triangle of first kind read by rows: T(n, k) = [x^k] ∏_m=1..n (x - m - r), with r = 4. A49460

Triangle generated by the asymptotic expansions of the E(x,m=2,n). A165674

Triangle read by rows. T(n, k) = (n - k + 1)! * H(k, n - k), where H are the hyperharmonic numbers. For 0 <= k <= n. A165675

Array read by descending antidiagonals: A(n, k) = (n + 1)! * H(k, n + 1), where H(n, k) is a higher-order harmonic number, H(0, k) = 1/k and H(n, k) = ∑_j=1..k H(n-1, j), for 0 <= k <= n. A105954

Numbers which are the sum of their proper divisors containing the digit 7. A59466

Dimension of 5-variable non-commutative harmonics (twisted derivative). The dimension of the space of non-commutative polynomials in 5 variables which are killed by all symmetric differential operators (where for a monomial w, d_ξ ( ξ w ) = w and d_ξ ( xj w ) = 0 for i/=j). A122369
