Bourgoin, Plate 36

• The symmetry group of the tiling is *632 (p6m).
• All the internal angles of the constituent polygons are a multiple of 15°.
• Contains one regular 12-pointed star polygon with vertex angle of 90°.
• There are five non-regular reflective tiles.
• The tiling is edge-to-edge.
• As drawn, contains about 305 polygons.
