Symmetries, Patterns, and Orbifolds
featuring Dr. Tim Perutz

On Saturday September 15, 2012, Dr. Tim Perutz lead a discussion about wallpaper patterns and different kinds of symmetries using rotations, reflections, and glides. We learned how to tell if two patterns are alike using invariants, and we identified and constructed orbifolds from some Frieze patterns. We also learned how to identify orbifolds according to their signature.
