• The symmetry group of the tiling is *632 (p6m).
• All the internal angles of the constituent polygons are a multiple of 20°.
• Contains one regular 6-pointed star polygon with vertex angle of 60°.
• Contains one regular 9-pointed star polygon with vertex angle of 80°.
• There are four non-regular reflective tiles.
• The tiling satisfies the interlace condition and has one finite interlace and one infinite interlace.
• The tiling is edge-to-edge.
• As drawn, contains about 248 polygons.
