• Percolation series for f.c.c. lattice.at n=16A006806
• G.f. is 1/F, where x*F is g.f. for Fibonacci word (A003849).at n=61A080845
• 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=29A137296
