In geometry, the truncated square tiling is a semiregular tiling of the Euclidean plane. There is one square and two octagons on each vertex. This is the only edge-to-edge tiling by regular convex polygons which contains an octagon. It has Schläfli symbol of t0,1{4,4}.
Conway calls it a truncated quadrille.
Other names used for this pattern include Mediterranean tiling and octagonal tiling.
It is topologically related to the polyhedron truncated octahedron, 4.6.6
There are 3 regular and 8 semiregular tilings in the plane.
There are two distinct uniform colorings of a truncated square tiling. (Naming the colors by indices around a vertex (4.8.8): 122, 123.)
2 colors: 122 |
3 colors: 123 |
