Tiling derived from a Roman Mosaic

• The symmetry group of the tiling is *442 (p4m).
• All the internal angles of the constituent polygons are a multiple of 9°.
• Contains one regular two-pointed star polygon with vertex angle of 117°.
• Contains one regular four-pointed star polygon with vertex angle of 63°.
• Contains one regular 8-pointed star polygon with vertex angle of 18°.
• The tiling satisfies the two-colour condition.
• The tiling is edge-to-edge.
• As drawn, contains about 52 polygons.
