   In Cayley-Dickson construction I changed

   $1 := (0,1)$

   and

   $1^2 = -1$

   to $e:=(0,1)$ and $e^2 = -1$ respectively, and flagged this. Is this what you meant, Toby?

Actually, the mistake was that I'd written "octonion" in the first place. Fixed (and David's question answered, and some other changes, including the introduction of a symbol for the entire algebra).

   Format: MarkdownItex@ David Yes, and this is what it said before; I was just confused when I changed it. I'm going to now change $e$ to $i$ because then I won't be confused the next time!
