Some tiles associated with the 6th unit cubic Pisot number

Order 7 Demisymmetric Tiles (4c²+c³+2c⁴)

I. all pairs of elements merged

Of the 8 figures with all 3 pairs of elements are colocated, 2 are implementations of the order 3 demisymmetric tiles, and 1 is 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.
