English: A Cairo pentagonal tiling, formed by overlaying two perpendicular hexagonal tilings, each formed by flattening a regular hexagonal tiling by a factor of in perpendicular directions. The resulting pentagonal tiles can be given integer coordinates (±2,0), (±3,3), (0,4). Unlike many other forms of the Cairo tiling, each edge is collinear with infinitely many other edges.
