Example of an Egyptian design with wallpaper group p4m. A wallpaper group (or plane symmetry group or plane crystallographic group) is a mathematical classification of a two-dimensional repetitive pattern, based on the symmetries in the pattern.

The 17 wallpaper groups, with finite fundamental domains, are given by International notation, orbifold notation, and Coxeter notation, classified by the 5 Bravais lattices in the plane: square, oblique (parallelogrammatic), hexagonal (equilateral triangular), rectangular (centered rhombic), and rhombic (centered rectangular).
English: A 4 co-uniform tiling with wallpaper group p4g, colored by planigon. Only contains obtuse triangles (O) and tie kites (T) with co-uniformity 3:1, so every plangion is a clock one. This is the small fractalization (variation) of the snub square tiling, with ratio 2+√3.
