Groups isomorphic to their non-nilpotent subgroups
Groups isomorphic to their non-nilpotent subgroups
We were concerned in [12] with groups G that are isomorphic to all of their non-abelian subgroups. In order to exclude groups with all proper subgroups abelian, which are well understood in the finite case [7] and which include Tarski groups in the infinite case, we restricted attention to the …
