The Oberwolfach Problem
Between his junior and senior years, Ambrose Sterr '07 did some research work with me on the Oberwolfach Problem. The problem concerns arranging the mealtime seating of mathematicians at a conference so that each of them sits next to every other during the course of the conference. We'll spend a class playing with this puzzle, and consider what Ambrose and I achieved and what is still to be done.
