• The symmetry group of the tiling is *632 (p6m).
• All the internal angles of the constituent polygons are a multiple of 60°.
• Contains two regular hexagons.
• Contains one regular 6-pointed star polygon with vertex angle of 60°.
• There is one non-regular reflective tile.
• The tiling satisfies the interlace condition and has no finite interlace and one infinite interlace with straight cross-overs.
• The tiling is edge-to-edge.
• As drawn, contains about 173 polygons.
