Geometry
- The symmetry group of the tiling is *442 (p4m).
- All the internal angles of the constituent polygons are a multiple of 22.5°.
- Contains two squares.
- Contains two regular 8-pointed star polygons with vertex angle of 90°.
- There are 6 non-regular reflective tiles (including one kite).
- The tiling satisfies the interlace condition and has two finite interlaces and no infinite interlace with straight cross-overs.
- The tiling is edge-to-edge.
- As drawn, contains about 290 polygons.
