• The symmetry group of the tiling is 4*2 (p4g).
• All the internal angles of the constituent polygons are a multiple of 30°.
• Contains two squares.
• Contains three regular hexagons.
• Contains one regular 6-pointed star polygon with vertex angle of 60°.
• There is one non-regular reflective tile and one reflective pair.
• The tiling satisfies the two-colour condition.
• The tiling is not edge-to-edge.
• As drawn, contains about 265 polygons.
