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 and edge if and only if G
contains an element of order pq. The prime graph of
G is the denoted by Γ(G). Mina Hagie (Comm. Algebra, 2003) determined finite groups G such that Γ(G)=Γ(S), where S is a sporadic simple group. In this paper we determine finite groups G such that Γ(G)=Γ(L2(q)) for some q < 100. Download TeX format |
