• Number of 4-step knight's tours on an (n+2) X (n+2) board summed over all starting positions.at n=12A186853
• Number of partitions p of n such that the number of parts having multiplicity 1 is not a part and max(p) - min(p) is not a part.at n=49A241450
• Triangle of number of connected subgraphs of K(n,n) with m edges.at n=29A255192
• 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 triangular lattice with periodic boundary conditions. This is for the probability that it wraps in both dimensions.at n=54A365948
