MAXWELL LEVINE

This paper discusses plane symmetry groups, also known as planar crystallographic groups or wallpaper groups. The seventeen unique plane symmetry groups describe the symmetries found in two-dimensional patterns such as those found on weaving patterns, the work of the artist M.C. Escher, and of course wallpaper. We shall discuss the fundamental components and properties of plane symmetry groups.
