Geometry
- The symmetry group of the tiling is *632 (p6m).
- All the internal angles of the constituent polygons are a multiple of 5°.
- Contains one regular 8-pointed star polygon with vertex angle of 90°.
- Contains one regular 12-pointed star polygon with vertex angle of 60°.
- Contains one regular 24-pointed star polygon with vertex angle of 40°.
- There are 6 non-regular reflective tiles (including 3 kites) and four reflective pairs.
- The tiling satisfies the interlace condition and has no finite interlace and three infinite interlaces with straight cross-overs.
- The tiling is edge-to-edge.
- As drawn, contains about 1849 polygons.
