Symmetric Group

 

A symmetric group of order n is a group consisting of all possible permutations of n objects. Such a group has n! elements. The permutations of n objects with an even number of inversions form an alternating subgroup of the symmetric group; this alternating subgroup has n!/2 elements.

Our interest in this result stems from the crucial role it plays in Quillen's method [8] for proving homological stability of the symmetric groups. Following Hatcher and Wahl [5], we shall formulate and prove a slightly more general theorem so that it can be applied in the proof of homological stability of wreath-product groups.
