Some tiles associated with the 6th unit cubic Pisot number

Order 7 Paraallosymmetric Tiles

I. Some compact complex teragons

There are two sets of paraallosymmetric tiles with dissection equation c+c2+3c3+c4+c5. These are some of the complex teragons from one of those sets, shown together with their unit cells.

In the case of the first, not only do 6 copies make a symmetric tile (as is the case for all the order 7 paraallosymmetric tiles), but three copies make up one of the demisymmetric tiles.
