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

## Order 7 Demisymmetric Tiles
(4c^{2}+c^{3}+2c^{4})

## IV. short diagonal c^{2} and
c^{4} elements merged

There are 8 tiles in with the short diagonal c^{2} elements are
colocated and the c^{4} elements are also colocated.

One of the tiles is "compact" (without voids); the remaining seven have
voids, and when the weight function is plotted show a ribbon (in green) where
only have the corresponding area of the plane is covered by the tile.

Two copies can (obviously) be put together to tile a symmetric tile. The
images below show one copy in red, and a copy rotated 180° in blue; the
overlapping areas (the ribbons) are shown in magenta.
