• Number of ways to place zero or more nonadjacent 0,0 1,0 2,1 2,2 3,3 4,3 5,4 5,5 polyhexes in any orientation on a planar nXnXn triangular grid.at n=8A155413
• Take a squarefree semiprime and take the difference of its prime factors. If it is a squarefree semiprime repeat the process. Sequence lists the squarefree semiprimes that generate other squarefree semiprimes only in the first k steps of this process. Case k = 5.at n=23A296812
• Square array T(n,k), n >= 1, k >= 2, read by antidiagonals, where T(n,k) is the number of Hamiltonian paths in the n X k grid graph which start at any of the n vertices on left side of the graph and terminate at any of the n vertices on the right side.at n=62A333571
• Numbers k such that w(k), w(k+1), and w(k+2) are all odd, where w is A336957.at n=18A337644
• Number of compositions (ordered partitions) of n into distinct decimal palindromes.at n=35A338847
