Geometry
- The symmetry group of the tiling is *442 (p4m).
- All the internal angles of the constituent polygons are a multiple of 45°.
- Contains one regular octagon.
- Contains one regular 8-pointed star polygon with vertex angle of 45°.
- There are two non-regular reflective tiles (including one kite).
- The tiling satisfies the interlace condition and has one finite interlace and no infinite interlace with straight cross-overs.
- The tiling is edge-to-edge.
- As drawn, contains about 175 polygons.
