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 two-pointed star polygon with vertex angle of 60°.
- Contains three regular hexagons.
- Contains two regular 6-pointed star polygons with vertex angle of 60°.
- There are three non-regular reflective tiles (including one kite).
- The tiling satisfies the interlace condition and has two finite interlaces and no infinite interlace with straight cross-overs.
- The tiling is edge-to-edge.
- As drawn, contains about 393 polygons.
