Geometry
- The symmetry group of the tiling is 2*22 (cmm).
- All the internal angles of the constituent polygons are a multiple of 3.21 (π/56)°.
- Contains one regular two-pointed star polygon with vertex angle of 77.14 (3π/7)°.
- Contains one regular 7-pointed star polygon with vertex angle of 77.14 (3π/7)°.
- Contains one regular 14-pointed star polygon with vertex angle of 70.71 (11π/28)°.
- There are 15 non-regular reflective tiles (including 5 kites) and two reflective pairs.
- The tiling satisfies the interlace condition and has 6 finite interlaces and no infinite interlace with straight cross-overs.
- The tiling is edge-to-edge.
