Geometry
- The symmetry group of the tiling is *442 (p4m).
- All the internal angles of the constituent polygons are a multiple of 6.42 (π/28)°.
- Contains two regular two-pointed star polygons with vertex angle of 25.71 (π/7)°.
- Contains one regular four-pointed star polygon with vertex angle of 64.28 (5π/14)°.
- Contains one regular 8-pointed star polygon with vertex angle of 109.28 (17π/28)°.
- The tiling satisfies the two-colour condition.
- The tiling is edge-to-edge.
- As drawn, contains about 73 polygons.
