Bourgoin, Plate 141

• The symmetry group of the tiling is *632 (p6m).
• All the internal angles of the constituent polygons are a multiple of 15°.
• Contains two regular hexagons.
• Contains one regular four-pointed star polygon with vertex angle of 120°.
• Contains one regular 6-pointed star polygon with vertex angle of 60°.
• Contains one regular 12-pointed star polygon with vertex angle of 60°.
• There are three non-regular reflective tiles and two tiles with no mirror image.
• 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 346 polygons.
