Seminar: Jumping through Permutation Patterns: Gray Codes for Catalan Structures, Rectangulations, and more!

Abstract: In 1677 Fabian Stedman published a book on bell-ringing called Campanalogia. This book described a pattern of permutations which came to be known as plain changes to bell ringers and the Steinhaus-Johnson-Trotter algorithm for mathematicians and computer scientists.
