Given a general element u of the Clifford algebra Cl_p,q (R) and an
(anti-)automorphism * on the same algebra; is it possible to
consistently define * for all p,q so that it becomes isomorphic to the
"reversion" operation defined for p=q=1? If it is not possible to
define such a * for general p,q, under what conditions is such an
operation (consistently) definable?

As an aside, is "reversion" defined for Cl_2,0 (R) and Cl_0,2 (R) in
the same manner as for Cl_1_1 (R) ?

Thanks in advance
