If you have a question about this talk, please contact Chris Bowman. Given a finite set of elements in a group or a ring, an ordering of the elements must be chosen before they can be lined up and composed. I will discuss the kind of algebra where compositions are instead indexed by an n-tuple of distinct points in the plane. I will give examples, some of which may be familiar (although you might not have guessed it). My final example comes from a modern approach to the ancient art of origami.
