On the prime graphs of the automorphism groups of sporadic simple groups
In this paper as the main result, we determine finite groups with the same prime graph as the automorphism group of a sporadic simple group, except .
On the recognizability of some projective general linear groups by the prime graph
Let be a finite group. The prime graph of is a simple graph whose vertex set is and two distinct vertices and are joined by an edge if and only if has an element of order . A group is called -recognizable by prime graph if there exist exactly nonisomorphic groups satisfying the condition . A 1-recognizable group is usually called a recognizable group. In this problem, it was proved that is recognizable, if is an odd prime and is odd. But for even , only the recognizability...
