Geometry
- The symmetry group of the tiling is *632 (p6m).
- All the internal angles of the constituent polygons are a multiple of 30°.
- Contains one regular three-pointed star polygon with vertex angle of 60° - composed of kites.
- Contains one regular 12-pointed star polygon with vertex angle of 90°.
- There are two non-regular reflective tiles (including 2 kites) and one reflective pair.
- The tiling does not satisfy the two-colour condition.
