Notes
Peter Rowlett (6 September 2022):
Book first published 1989. No other dates given on copyright page, but presumably the articles aren't all from 1989.
Peter Rowlett (6 September 2022):
I had thought this might be 'The flip-strip sonnet, the lipogram and other mad modes of wordplay', but the next chapter says this one inspired an article in Time on 10 Jan 1977 and 'The flip-strip sonnet...' was the Feb 1977 article. Is it likely the Feb issue of Scientific American appeared early enough to have inspired a Time article on 10 Jan?
Peter Rowlett (12 August 2023):
Mathematical Magic Show page 134 says the February 1977 column is about OuLiPo. So despite the timing above, I've assigned this chapter to this article. I've chosen chapter 6 over chapter 7 because it seems likely chapter 7 was written specially for the book (see note there).

I have seen this chapter and column side-by-side and they match.
