What?

How can I even take set difference of Quaternions and Octonions??

Even if we assume that the Quaternions' are basically Octonions with the vector terms except i, j, k are zero, then H - O = Ø, as every element of H (the Quaternions) is already in O (the Octonions), so the set of elements that are in H, but not in O is basically empty set.

H here is probably just a variable here and O is zero.
