Consider the 2n symbols x1, . . . , xn, x−1 1 , . . . , x −1 n . Collect these into a set G. There is a map from G to itself which interchanges xi and x−1 i . This map is denoted by the usual inversion symbol g 7→ g−1. Thus x−1 i is unambiguous and (x −1 i ) −1 = xi. The empty word will be denoted by 1. A word is defined to be a finite ordered list of elements of G, depicted as exemplified by x...
