This solution is so easy! The question had initially stumped me, but if I had known that the Concatenate function in "Summarize" creates the result in alphabetical order, I would have been able to solve it much faster. Thank you for this solution!

This technique will be useful in my day job, for assessing the course combinations taken by students throughout their academic careers and correlating that with success in outcomes, and particularly with university applications.  Very cool and thought provoking, even though it seems simple at first! Thanks for the challenge.
