On Posets of Classes of Subgroups with Same Set of Orders of Elements
Sachin Ballal, Tushar Halder
In this paper, we study the posets of classes of subgroups of finite group having same set of orders of elements. We show that this poset is a chain only in the case of p-groups an…

On Posets of Classes of Automorphic Subgroups of Finite Groups
Sachin Ballal, Tushar Halder
In [16], Tarnauceanu studied the poset Iso(G), of isomorphic classes of subgroups of a finite group G and proposed several questions for further research. In this paper, we study t…
