Bourgoin, Plate 85

• The symmetry group of the tiling is *632 (p6m).
• All the internal angles of the constituent polygons are a multiple of 30°.
• Contains one regular three-pointed star polygon with vertex angle of 60° - composed of kites.
• Contains one regular 12-pointed star polygon with vertex angle of 90°.
• There are two non-regular reflective tiles (including 2 kites) and one reflective pair.
• The tiling does not satisfy the two-colour condition.
• The tiling is edge-to-edge.
• As drawn, contains about 352 polygons.
