Bourgoin, Plate 183

• The symmetry group of the tiling is 2*22 (cmm).
• All the internal angles of the constituent polygons are a multiple of 18°.
• Contains one regular pentagon.
• Contains one regular decagon.
• Contains one regular 10-pointed star polygon with vertex angle of 108°.
• There are four non-regular reflective tiles.
• 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 392 polygons.
