Question: How do you make functions invariant under a given frieze group, and how many of these groups are there? Every symmetry of a rosette pattern necessarily fixes the origin of our plane—rather a stern limitation on a pattern. Friezes—patterns invariant under translations in a single direction—provide a next natural category of symmetry groups, where the origin is allowed to echo through a pattern in a limited way.
Named for an architectural feature—a band of decor below a roofline—friezes are seen in many other places than building exteriors. Look for them in wallpaper bands along
