**Some tiles associated with the 6th unit cubic Pisot number**

## IV. Complex
Teragons (2nd group)

There are a considerable number of order 7 complex teragons, including 24
with outlines similar to the order 5 asymmetric partial postcomposition
derivatives of the symmetric tile, but
incorporating voids. The 12 similar to one of the asymmetric partial
postcomposition derivatives are shown below.

The distribution of solid and void areas is more easily seen when the weight
function is plotted, as below.

The unit cells are shown below. It is not obvious from visual inspection
that the 6 copies make up a unit cell, but this is confirmed by plotting the
weight function for the unit cell.
