Clifford Algebras, Clifford Groups, and the Groups ,(,) and ,(,),roup .(.) is simply connected (a fact that it is not so easy to prove without some machinery), whereas .(.) is not simply connected. Intuitively speaking, .(.) is more twisted than .(.). In fact, we will see that .(.) is a double cover of .(.).

Exterior Tensor Powers and Exterior Algebras,In this chapter we consider . (also called .) multilinear maps and . (also called .), denoted .. In many respects alternating multilinear maps and exterior tensor powers can be treated much like symmetric tensor powers, except that sgn(.) needs to be inserted in front of the formulae valid for symmetric powers.
