Holor

A holor (/ˈhoʊlər/; Greek ὅλος "whole") is a mathematical entity that is made up of one or more independent quantities ("merates" as they are called in the theory of holors). Complex numbers, scalars, vectors, matrices, tensors, quaternions, and other hypercomplex numbers are kinds of holors. If proper index conventions are maintained then certain relations of holor algebra are consistent with that of real algebra; i.e. addition and uncontracted multiplication are both commutative and associative.
