Notes
Peter Rowlett (5 November 2023):
Opening refers to this as being instead of an addendum for the previous chapter, so presumably written for the book.
Peter Rowlett (5 November 2023):
I have assigned all but one Mathematical Games column to a book chapter, and I have four other articles by Martin Gardner in Scientific American which do no correspond to chapters. I have inspected this chapter in reference to these five articles and there is no match. I conclude this was not originally a Scientific American column.
