• McKay-Thompson series of class 18f for the Monster group.at n=40A058544
• T(n, k) is the coefficient of z^k in the numerator of the polynomial part of z^n*exp(-n*s), where s = hypergeom([1, 1, 3/2], [2, 5/2], 1/z^2)/(6z^2); related to Chebyshev's quadrature. Triangle read by rows, T(n,k) for 0 <= k <= n.at n=38A101270
• Matrix inverse of A008278, which is the reflected triangle of the Stirling numbers of 2nd kind.at n=15A106342
• Column 0 of triangle A106342, which is the matrix inverse of the triangle A008278 of Stirling numbers of 2nd kind.at n=5A106343
