Bourgoin, Plate 106

• The symmetry group of the tiling is *442 (p4m).
• All the internal angles of the constituent polygons are a multiple of 15°.
• Contains one regular three-pointed star polygon with vertex angle of 90°.
• Contains one regular four-pointed star polygon with vertex angle of 120°.
• Contains one regular 6-pointed star polygon with vertex angle of 30°.
• Contains one regular 8-pointed star polygon with vertex angle of 75°.
• There are two non-regular reflective tiles and one reflective pair.
• The tiling satisfies the interlace condition and has no finite interlace and two infinite interlaces.
• The tiling is edge-to-edge.
• As drawn, contains about 235 polygons.
