Bertfried,
Thanks this looks very useful.
Can I ask about the definitions of the involutions:
gradeInvolution == reversion? sign=(-1)^(d(d-1)/2) symbol= ~
Cliplus clirev == ? symbol=multiply by pseudoscalar? symbol=
Clifford conjugation: scalar part minus non-scalar part? symbol=
I know these are wrong but I just made a guess!
I expect I had better ignore the Spinors for now although I am curious about
how they should be added on later. Upto now I have thought of spinors as an
even subalgebra of Clifford algebras? (rotation by 2*pi multiplies by -1) but
this does not seem to be the case here? Would spinors require a new type of
multiplication or a new domain?
