Geometry
- The symmetry group of the tiling is 2*22 (cmm).
- All the internal angles of the constituent polygons are a multiple of 25.71 (π/7)°.
- Contains two regular two-pointed star polygons with vertex angle of 77.14 (3π/7)°.
- Contains one regular 14-pointed star polygon with vertex angle of 77.14 (3π/7)°.
- There are five non-regular reflective tiles (including 2 kites) and two reflective pairs.
- The tiling satisfies the interlace condition and has four finite interlaces and no infinite interlace with straight cross-overs.
- The tiling is edge-to-edge.
- As drawn, contains about 344 polygons.
