چکیده
|
In this paper, we continue the study of the subgroup inclusion graph in(f ) on a free group with finiterank f , where the vertex set is the collection of non-trivial proper subgroups of a free group with finiterank and two vertices are adjacent if one is contained in other. we show that in(f ) is perfect.
