wallpaper group




A wallpaper group is a crystallographic group (space group) in dimension 2, hence a subgroup GIso( 2)G \subset Iso(\mathbb{R}^2) of the isometry group of the Euclidean plane such that

  1. the part of GG inside the translation group is generated by two linearly independent vectors;

  2. the point group is finite.
