I am reading
and I was wondering : what is the most efficient way to work out basic combinations of bivectors (or trivectors...)
Suppose for instance I have a 4-dimensional space with basis (e1,e2,e3,e4) and I would want to work out
(e_1 -e2+ e3) wedge (e_2-e_4),
how could I do this?
(I just think working with big tables with many zero entries is a bit over the top for my purposes)
