• Number of -n..n arrays x(0..4) of 5 elements with zero sum and no two or three adjacent elements summing to zero.at n=16A200432
• The orbit of n under iterations of x -> concatenate(A048762(x), A055400(x)) enters a pseudo-loop x(k) = a^3 * 10^((k-k0)*A055642(b)) + b for k > k0. This sequence lists the b-value.at n=24A369861
