Geometry
- The symmetry group of the tiling is *632 (p6m).
- All the internal angles of the constituent polygons are a multiple of 8.57 (π/21)°.
- Contains one regular two-pointed star polygon with vertex angle of 34.28 (4π/21)°.
- Contains one regular three-pointed star polygon with vertex angle of 25.71 (π/7)°.
- The tiling satisfies the interlace condition and has no finite interlace and one infinite interlace with non-straight cross-overs.
- The tiling is edge-to-edge.
- As drawn, contains about 75 polygons.
