40 ,Ion, Armeanu, Didem Ozturk The alternating groups represent a very important class of groups. The group An is abelian if and only if n ≤ 3 and simple if and only if n = 3 or n ≥ 5 ([6], p. 295). A5 is the smallest non-abelian simple group (having order 60), and the smallest non-solvable group.

The ,centralizer element, (PLC) is an additional failure point for the system. There is no ,cent ralizer element,, thus eliminating a possible failure point. Sensors must be dedicated for connection to the PLC, thus leading to eventual duplication of sensors and additional costs in monitoring systems.

Hence there must be an ,element, s in S such that t = xs acts non-trivially on each root space. In this case t is a regular ,element, of T—the identity component of its ,centralizer, in G equals T. There is a unique Weyl alcove A in such that t lies in exp A and 0 lies in the closure of A.

about CG(M), the ,centralizer, of M in G, and thus we shall investigate faithful re-presentations. To express our main results we shall make the following definition, following Roseblade(ll): Suppose that G is a group and X an Gy acts set o. n which Then we say that an ,element, x of G-orbital X is if x has only finitely many distinct images under G.
