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

## Order 7 Demisymmetric Tiles
(2c+2c^{4}+2c^{7}+c^{10})

## I. all pairs merged

Of the 8 figures with all three pairs of elements merged 2 are the same as
order 3 demisymmetric tiles and 2 the same as order 5 demisymmetric tiles. The
remaining 4 are shown below.

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.
