quaternions are associative! Anyway, you can clever code all the algebraic operations of quaternions into matrices and go with that!

Yeah, but octonions are not associative. Which is what the poster was saying. (By the way, that also means that there isn't a matrix representation for octonions, since matrix multiplicative is associative).
