A wallpaper group is a classification of two-dimensional repeating patterns, which can be used to describe the symmetry and structure of various kinds of tiling and decorative designs. In mathematical terms, a wallpaper group is one of the 17 different groups that describe the possible patterns that can be formed on a plane, where each pattern can be generated by translations, rotations, reflections, and glide reflections.
