- Contains one regular 6-pointed star polygon with vertex angle of 90° - composed of kites.
- Contains one regular 12-pointed star polygon with vertex angle of 90° - composed of kites.
- There are four non-regular reflective tiles (including 3 kites).
- The tiling does not satisfy the two-colour condition.
