A214122 Irregular array T(n,k) of the numbers of non-extendable (complete) non-self-adjacent simple paths ending at each of a minimal subset of nodes within a square lattice bounded by rectangles with nodal dimensions n and 4, n >= 2.
10, 0, 33, 6, 4, 0, 90, 22, 22, 4, 256, 52, 67, 14, 88, 32, 720, 104, 187, 30, 236, 108, 1931, 200, 495, 56, 622, 262, 602, 364, 5029, 386, 1245, 106, 1624, 618, 1537, 898, 12996, 744, 3061, 206, 4080, 1502, 3938, 2186, 3744, 2196, 33512, 1422, 7615, 398

Examples
When n = 2, the number of times (NT) each node in the rectangle is the end node (EN) of a complete non-self-adjacent simple path is EN 0 1 2 3 4 5 6 7 NT 10 0 0 10 10 0 0 10 To limit duplication, only the top left-hand corner 10 and the 0 to its right are stored in the sequence, i.e. T(2,1) = 10 and T(2,2) = 0.
