%N Irregular array T(n,k) of the numbers of non-extendable (complete) non-self-adjacent simple paths incorporating each of a minimal subset of nodes within a square lattice bounded by rectangles with nodal dimensions n and 2, n >= 2.
%C The subset of nodes is contained in the top left-hand quarter of the rectangle and has nodal dimensions floor((n+1)/2) and 1 to capture all geometrically distinct counts.
%C The quarter-rectangle is read by rows.
%C The irregular array of numbers is:
%C ....k....1....2....3....4....5....6....7....8....9...10
%C ..n
%C ..2......6
%C ..3.....12...14

%C where k indicates the position of a node in the quarter-rectangle.
%C For each n, the maximum value of k is floor((n+1)/2).
%C Reading this array by rows gives the sequence.

%e When n = 2, the number of times (NT) each node in the rectangle (N) occurs in a complete non-self-adjacent simple path is
%e N 0 1
%e 2 3
%e NT 6 6
%e 6 6
%e To limit duplication, only the top left-hand corner 6 is stored in the sequence, i.e. T(2,1) = 6.
