• The symmetry group of the tiling is *442 (p4m).
• All the internal angles of the constituent polygons are a multiple of 45°.
• Contains two squares.
• Contains one regular 8-pointed star polygon with vertex angle of 90°.
• There are two non-regular reflective tiles (including one kite).
• The tiling satisfies the two-colour condition.
• The tiling is not edge-to-edge.
• As drawn, contains about 317 polygons.
