• This table (read by rows) shows the coefficients of sum formulas of n-th subfactorial numbers (A000166). The n-th row (n>=1) contains T(i,n) for i=1 to n, where T(i,n) satisfies Subf(n) = Sum_{i=1..n} T(i,n) * n^(n-i).at n=26A101559
• Expansion of x^2*(-3+4*x)/(1-x^3+x^4).at n=41A110061
• Fibonacci central tridiagonal matrices as a triangular sequence from a recursive polynomial definition.at n=29A123974
• G.f. A(x) satisfies 1 = Sum{n=-oo..+oo} (x^n - 2*x*A(x)^n)^n.at n=6A383564
