Octonions are an extension to the complex numbers, similar to quaternions. But whereas quaternions are quadruplets of real numbers, octonions are octets; and whereas in quaternions multiplication is not commutative, in octonions it isn't associative either.
The octonions were discovered by [John T. Graves]? in 1843, and independently by [Arthur Cayley]?, who published the first paper on them in 1845. They are sometimes called Cayley numbers.
