The document discusses the class scheduling for a school's senior, junior, and part-time faculty for the next semester. Senior faculty are scheduled to teach on Mondays, Wednesdays, and Fridays, while junior faculty teach on Mondays, Tuesdays, and Wednesdays. The schedule for part-time faculty is still undetermined. The document asks if the sets of days scheduled for senior and junior faculty are considered two equivalence classes.
