EXAMPLE

a(3) = 88 as, in the first quadrant, the three 3step SAWs that have the first and last visited lattice point being mutually visible are:
.
X

X. . X
  
X. X. X..
.
The sum of square endtoend displacements of these three walks is 1 + 5 + 5 = 11. They can be walked in eight different ways on a square lattice thus a(3) = 11 * 8 = 88.
