Point your browser to "http://iris.ifisicacu.unam.mx/software.html" for 
"Clifford: Mathematica package for calculations with Clifford Algebra".

In my article "Clifford algebra calculations with a microcomputer", pp.
39-55, published in A. Micali et al. (eds.): "Clifford Algebras and 
their Applications in MathematicalPhysics", Kluwer, 1992, I compare
advantages and disadvantages of various computer programs in doing
Clifford algebras.  In general, symbolic programs are not efficient in
multililinear algebra, for reasons explained in the Section 2 "Why a
numerical, not symbolic program?", pp. 40-41, of my article.

I have developed a numerical, but quasisymbolic program for real non-
degenerate Clifford algebras, CLICAL.  You may download CLICAL from
"http://www.hit.fi/~lounesto/CLICAL.htm". --
