- ItemOn finite groups having perfect order subsets(Hikari Ltd, 2009) Das, Ashish KumarA finite group G is said to be a POS-group if for each x in G the cardinality of the set {y ∈ G|o(y) = o(x)} is a divisor of the order of G. In this paper we study some of the properties of arbitrary POS-groups, and construct a couple of new families of nonabelian POS-groups. We also prove that the alternating group An, n ≥ 3, is not a POS-group.
