Bourgoin, Plate 41

• 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 two-pointed star polygons with vertex angle of 60°.
• Contains one regular 12-pointed star polygon with vertex angle of 60° - composed of kites.
• There are two non-regular reflective tiles (including 2 kites) and two reflective pairs.
• The tiling does not satisfy the two-colour condition.
• The tiling is edge-to-edge.
• As drawn, contains about 296 polygons.
