Geometry
- The symmetry group of the tiling is *442 (p4m).
- All the internal angles of the constituent polygons are a multiple of 11.25°.
- Contains one regular four-pointed star polygon with vertex angle of 67.5° - composed of kites.
- Contains one regular 8-pointed star polygon with vertex angle of 90° - composed of kites.
- There are three non-regular reflective tiles (including 2 kites) and three reflective pairs.
- The tiling does not satisfy the two-colour condition.
- The tiling is not edge-to-edge.
- As drawn, contains about 534 polygons.
