چکیده
|
Let g be a nite group. in [ghasemabadi et al., characterizations of the simple group2dn(3) by prime graph and spectrum, monatsh math., 2011] it is proved that if n is odd, then 2dn(3)is recognizable by prime graph and also by element orders. in this paper we prove that if n is even,then d = 2dn(3) is quasirecognizable by prime graph, i.e. every nite group g with ??(g) = ??(d) hasa unique nonabelian composition factor and this factor is isomorphic to d.
