I'm also interested in exterior algebras, as well as Clifford algebra. During Sage Days 10, I did a little work to try to integrate my GluCat library ( http://glucat.sf.net ) into Sage, but only got as far as having a working Cython interface ( http://wiki.sagemath.org/days10/CodingSprint ). What was missing was integration into the coercion system ( http://www.sagemath.org/doc/reference/coercion.html ). If/when you do have exterior and Clifford algebras working, I'd very much like to understand your coercion model. My model would have each Clifford algebra R_{p,q} behave as if it was a subalgebra of the infinite dimensional algebra R_{\infty,\infty}, and would have canonical isomorphisms between R_{0,0} and R, R_{0,1} and C, and R_{0,2} and H.
