Subgroup Graphs of Finite Groups
Abstract
Let G be a fnite group with the set of subgroups of G denoted by S(G), then the subgroup graphs of G denoted by T(G) is a graph which set of vertices is S(G) such that two vertices H, K in S(G) (H not equal to K)
are adjacent if either H is a subgroup of K or K is a subgroup of H. In this paper, we introduce the Subgroup
graphs T associated with G. We investigate some algebraic properties and combinatorial structures of Subgroup
graph T(G) and obtain that the subgroup graph T(G) of G is never bipartite. Further, we show isomorphism
and homomorphism of the Subgroup graphs of finite groups.
