Abstract

The importance of the symmetric group is obvious from the fact that any finite group, of order n, say, is a subgroup of S n . The procedure for obtaining generators and relations for S n can be carried over almost unchanged for a certain infinite group, first studied by Artin (1926); accordingly, we begin by describing this so-called braid group. The symmetric group (§ 6.2, p. 64) has a subgroup An, of index 2 (§ 6.3, p. 66), which is particularly interesting because, when n > 4, it is simple. In § 6.4, p. 67, we exhibit the groups S3, A4, S4 and A5 as members of the family of polyhedral groups (l, m, n),defined by
.
