• The symmetry group of the tiling is *632 (p6m).
• All the internal angles of the constituent polygons are a multiple of (undefined).
• Contains one regular 12-pointed star polygon with vertex angle of 60°.
• Contains one regular 18-pointed star polygon with vertex angle of 40°.
• There are 8 non-regular reflective tiles and two reflective pairs.
• The tiling satisfies the interlace condition and has no finite interlace and one infinite interlace.
• The tiling is edge-to-edge.
• As drawn, contains about 781 polygons.
