    I did sedenions.

    I tunred the word “they” into “the sedenions”. Otherwise it sounded a bit like saying that the octonions are not a division algebra.

    In Cayley-Dickson construction I changed

    1:=(0,1)1 := (0,1)

    and

    1 2=11^2 = -1

    to e:=(0,1)e:=(0,1) and e 2=1e^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).

    @ David

    Yes, and this is what it said before; I was just confused when I changed it. I’m going to now change ee to ii because then I won’t be confused the next time!
