Cayley Numbers or Alternative Division Algebras by abandoning the vague principle of permanence, it was possible to create “out of nothing” new number systems which were still further removed from the real and complex numbers than were the quaternions. In December 1843 for example, only two months after Hamilton’s discovery, Graves discovered th
