Back in 2008, I said I was interested in adding support for Clifford algebras / Geometric Algebra to Sage. Since then I have found out that there is some support available in Axiom. Now that there is renewed interest in Exterior algebras, I would like to better understand how to incorporate bot

Hi Abraham, This sounds like a great project -- I've always wanted to read the Bryant/Griffiths books on EDS but I've always been too lazy to do the computations myself and get a proper grip on the subjects. Such a Sage package could be a great help. I'm not entirely happy with the way that the
