Everybody Loves Christopher Raymond

by Alex Vratsanos / Edited by George Barany

This Sunday-sized puzzle (21x21) honored a beloved math professor (photo on right) at the University of Delaware, who taught several courses that the constructor took during the 2012-2013 academic year. The puzzle was written circa April Fool's day, with a title that was a play on this, but not this TV show.
