• The symmetry group of the tiling is *442 (p4m).
• All the internal angles of the constituent polygons are a multiple of 7.5°.
• Contains five squares.
• Contains two regular two-pointed star polygons with vertex angle of 52.5°.
• Contains one regular 8-pointed star polygon with vertex angle of 45°.
• Contains one regular 12-pointed star polygon with vertex angle of 60°.
• There are 11 non-regular reflective tiles (including one kite) and two reflective pairs.
• The tiling satisfies the interlace condition and has five finite interlaces and no infinite interlace with straight cross-overs.
• The tiling is edge-to-edge.
• As drawn, contains about 833 polygons.
