Geometry
- The symmetry group of the tiling is 2*22 (cmm).
- All the internal angles of the constituent polygons are a multiple of 36°.
- Contains one regular two-pointed star polygon with vertex angle of 72°.
- Contains one regular 10-pointed star polygon with vertex angle of 72°.
- There are 6 non-regular reflective tiles (including one kite).
- The tiling satisfies the interlace condition and has one finite interlace and two infinite interlaces with straight cross-overs.
- The tiling is edge-to-edge.
- As drawn, contains about 444 polygons.
