Bourgoin, Plate 50

• The symmetry group of the tiling is *2222 (pmm).
• All the internal angles of the constituent polygons are a multiple of 22.5°.
• Contains two regular octagons.
• Contains one regular 8-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 one finite interlace and one infinite interlace with straight cross-overs.
• The tiling is edge-to-edge.
• As drawn, contains about 211 polygons.
