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

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

## II. both pairs of c^{2} elements
merged

Of the 8 figures with both pairs of c^{2} elements colocated, 3 are
disconnected, leaving 5 novel tiles, 4 of which have the larger elements merged
along the long side.

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.
