**TITLE: **On the Design of Diffusion Constants for Random Walks of

Squares, Triangles and
Cubes.

**ABSTRACT:**

We show how to design the value
of the diffusion constant D for the random walks of Squares and Triangles over
their respective regular lattice in two-dimensions, and for a random walk of a
Cube on the three-dimensional Cartesian lattice. By allowing movements to grid
locations other than nearest neighbors, we find that we can design the value of
the diffusion constant D to a value larger that unity (the default) or to a value
less than unity.
