TITLE: On the Design of Diffusion Constants for Random Walks of
Squares, Triangles and Cubes.
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.
