Periodic tiles and fixed points

There are two sets of tiles with period 7, shown in the second row and third row of the set of prototiles at the top above. For each tile, the iteration has the next tile in its center. The last tile in each row has the first tile at its center.

There is one fixed point vertex pattern in the tiling, emerging at every vertex, where the mandala below emerges with higher iterations. This mandala was created using the fifth iteration of the thin rhomb.
