Bourgoin, Plate 94

• The symmetry group of the tiling is *442 (p4m).
• All the internal angles of the constituent polygons are a multiple of 30°.
• Contains three equilateral triangles.
• Contains one regular four-pointed star polygon with vertex angle of 60°.
• Contains one regular four-pointed star polygon with vertex angle of 120°.
• Contains one regular 12-pointed star polygon with vertex angle of 90°.
• There are four non-regular reflective tiles (including one kite).
• The tiling satisfies the interlace condition and has three finite interlaces and no infinite interlace with straight cross-overs.
• The tiling is edge-to-edge.
• As drawn, contains about 615 polygons.
