• Numbers whose base-10 representation has exactly 6 runs.at n=6A043642
• Number of permutations of 1..n containing the relative rank sequence { 52341 } at any spacing.at n=4A158436
• Triangle read by rows: T(n,k) is the number of free polyforms consisting of k unit square cells and n-k isosceles right triangular cells whose short sides have unit length. Cells are joined along sides of equal lengths.at n=46A391193
• Array read by antidiagonals: Place k points in general position on each side of a regular n-gon and join every pair of the k*n boundary points by a chord; T(n,k) (n >= 3, k >= 0) gives the number of edges in the resulting planar graph.at n=49A392282
