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". -- Pertti Lounesto
