Bourgoin, Plate 152

• The symmetry group of the tiling is *442 (p4m).
• All the internal angles of the constituent polygons are a multiple of 2.81 (π/64)°.
• Contains one regular 8-pointed star polygon with vertex angle of 73.12 (13π/32)°.
• Contains one regular 16-pointed star polygon with vertex angle of 73.12 (13π/32)°.
• There are 18 non-regular reflective tiles (including 6 kites).
• The tiling satisfies the interlace condition and has 9 finite interlaces and no infinite interlace with straight cross-overs.
• The tiling is edge-to-edge.
• As drawn, contains about 1396 polygons.
