• Numbers k that divide the (left) concatenation of all numbers <= k written in base 11 (most significant digit on left).at n=31A029480
• Composite numbers k such that k*phi(k) is in A002378.at n=29A256545
• Irregular triangle read by rows: T(n,k) (0 <= k <= n^2) are coefficients of exact wrapping probability for site percolation on an n X n 2D nnsquare lattice with periodic boundary conditions. This is for the probability that it wraps around the vertical dimension.at n=53A366464
