Query: Cayley-Dicksonia Revisited   In the theory of the hypercomplex, the laws governing the algebra are based
on units that are naturally associated with an orthogonal vector space, a
requirement that is far from mandatory in many algebraic formulations arising
in the context of the reals or the complex numbers.In this article the
complementing view is held, in that the laws of hypercomplex algebra are recast
in terms of quite generally posited units. Proceeding in this manner, a
generalized form of the Cayley-Dickson process is examined. The representations
given are regular bimodular; the resulting matrices are standard except they
are allowed nonstandard multiplication for noncommutative matrix elements.
