• Antidiagonal triangular matrices of factorials as the example: M(3)={{0, 0, 1}, {0, 1, 2}, {1, 2, 6}}; the matrices are used to get characteristic polynomials and the triangular sequence is the coefficients of those characteristic polynomials.at n=26A137296
• Triangular sequence of coefficients based on a Hilbert Transform of A053120: Chebyshev T(x,n); Coefficients(A053120[n,m])-Floor[Imaginary part of( HilbertTransform(A053120(n,m))];.at n=60A137363
• G.f.: 1/(1 - x*d/dx log(eta(x))), where eta(x) is Dedekind's eta(q) function without the q^(1/24) factor.at n=27A283334
• Expansion of 1 / (1 + Sum_{k>=1} mu(k)^2 * x^k).at n=35A329099
• Expansion of 1 / Sum_{k>=0} x^(k*(3*k - 2)).at n=45A363275
