Chamfered square tiling
In geometry, the chamfered square tiling or semitruncated square tiling is a tiling of the Euclidean plane. It is a square tiling with each edge chamfered into new hexagonal faces. It can also be seen as the intersection of two truncated square tilings with offset positions. And its appearance is similar to a truncated square tiling, except only half of the vertices have been truncated, leading to its descriptive name "semitruncated square tiling". Usage and Names in tiling patterns. In floor tiling, this pattern with small squares has been labeled as "Metro Broadway Matte" and "alternate corner  square tile". With large squares it has been called a "Dijon tile pattern". As 3 rows of rectangles, it has been called a "basketweave tiling" and "triple block tile pattern ". Variations. Variations can be seen in different degrees of "truncation". As well, geometric variations exist within a given symmetry. The second row shows the tilings with a 45 degree rotation which also look a little different. Lower symmetry forms are related to the cairo pentagonal tiling with axial edges expanded into rectangles. The chiral forms be seen as two overlapping pythagorean tilings. Semikis square tiling. The dual tiling looks like  a square tiling with half of the squares divided into central triangles. It can be called a semikis square tiling, as alternate squares with kis operator applied. It can be seen as 4 sets of parallel lines.
