Geometry
- 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 6-pointed star polygon with vertex angle of 60°.
- Contains one regular 12-pointed star polygon with vertex angle of 60°.
- There are 7 non-regular reflective tiles (including 3 kites).
- The tiling satisfies the interlace condition and has two finite interlaces and one infinite interlace with straight cross-overs.
- The tiling is edge-to-edge.
