COMMENTS

There are two arrays (or lists, or vectors) involved, a length n+2 array with free elements from 0..k (thus (n+2)^(k+1) ^(n+2) of them) and an array that is being enumerated of length n, each element of the latter being the maximum of three adjacent elements of the first array.

There are two arrays (or lists, or vectors) involved, a length 9 n+2 array with free elements from 0..n k (thus 9^(n+2)^(k+1) of them) and an array that is that is being enumerated of length 7, n, each element of the latter being the maximum of three adjacent elements of the first array.
