Abstract
Let G be a finite group. We construct the prime graph of G as follows: the vertices of this graph are the prime divisors of |G| and two vertices p and q are joined by an edge if and only if G contains an element of order pq. The prime graph of G is denoted by Г(G).
Mina Hagie (Comm. Algebra, 2003) determined finite groups G such that Г(G) =Г(S), where S is a sporadic simple group. In this paper we determine finite groups G such that Г(G) = Г(L2(q)) for some...
