I'm playing with a Temperley-Lieb algebra with three strings,
i.e. an operator o, two generators A and B and a scalar t.
(AoA=t*A,BoB=t*B,AoBoA=A,BoAoB=B.)
Unluckily, AoB!=BoA, *and* I want to define some "mixes"
like w*A+x*B+y*AoB+z*BoA and multiply them, o shall be linear.
So e.g. (w*A+x*B)oA=w*(AoA)+x*(BoA)=w*A+x*(BoA).
How to implement? With o=** maybe (but does (x*A)**(y*B)
evaluate to x*y*(A**B)), and can I define "global rules"
that act automatically, just like I*I=-1)?
