Bourgoin, Plate 92

• 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 four-pointed star polygon with vertex angle of 60°.
• Contains one regular 6-pointed star polygon with vertex angle of 60°.
• Contains one regular 12-pointed star polygon with vertex angle of 120°.
• There are two non-regular reflective tiles (including 2 kites) and one reflective pair.
• 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 385 polygons.
