- The symmetry group of the tiling is *632 (p6m).
- All the internal angles of the constituent polygons are a multiple of 15°.
- Contains one regular three-pointed star polygon with vertex angle of 135°.
- Contains one regular 12-pointed star polygon with vertex angle of 75°.
- There are three non-regular reflective tiles (including one kite).
