The posets of classes of isomorphic subgroups of finite groups
Tarnauceanu, Marius
Original · EN
In this paper we introduce and study the poset of equivalence classes of subgroups of a finite group G, induced by the isomorphism relation. This contains the well-known lattice of solitary subgroups of G. We prove that in several particular cases it determines the structure of G.
