Geometry
- The symmetry group of the tiling is *632 (p6m).
- All the internal angles of the constituent polygons are a multiple of 30°.
- Contains two equilateral triangles.
- Contains one regular four-pointed star polygon with vertex angle of 60°.
- Contains one regular 12-pointed star polygon with vertex angle of 120°.
- There are four non-regular reflective tiles (including 2 kites).
- The tiling satisfies the interlace condition and has three finite interlaces and no infinite interlace with straight cross-overs.
- The tiling is edge-to-edge.
- As drawn, contains about 369 polygons.
