OEIS Sequences

Triangle of numerators of coefficients of Faulhaber polynomials in Knuth's version. A93556

Triangle read by rows, numerators of T(n,k) = (-1)ⁿ*binomial(n-1,k)*Bernoulli(n+k)/ (n+k) for n>=1, 0<=k<=n-1. A287703

Triangle read by rows: T(n,k) is the numerator of A(n,k), such that A(n,k) satisfies the identity for sums of odd powers: ∑_k=1..p k^2n-1 = 1/(2·n) * ∑_k=0..n-1 A(n,k) * (p²+p)^n-k, for all integers p >= 1. A385567

Numerator in Feinler's formula for unsigned Bernoulli number |B_2n|. A2443

Numerator of (2n+1)(2n+2) B_2n, where B_n are the Bernoulli numbers. Also numerators of the asymptotic expansion of the polygamma function ψ'''(z). A76549
