Isohedral Tiling

Let $S(T)$ be the group of symmetries which map a Monohedral Tiling $T$ onto itself. The Transitivity Class of a given tile T is then the collection of all tiles to which T can be mapped by one of the symmetries of $S(T)$. If $T$ has $k$ Transitivity Classes, then $T$ is said to be $k$-isohedral. Berglund (1993) gives examples of $k$-isohedral tilings for $k=1$, 2, and 4.
