For P an algebraic property of groups, we call a finitely presented group G “Universally-P” if both of the following occur: 1. G has property P. 2. Every finitely presented group H with property P embeds in G. Using the Higman embedding theorem, it has been shown that there exists a Universally-everything group; a finitely presented group in which every finitely presented group embeds. We will use some straightforward arguments to show that Universally-abelian groups do not exist (nor do Universally-nilpotent or Universally-soluble groups), yet universally-free groups do. Then, by closely analysing the Higman embedding theorem we will show that there exists a Universally-(torsion free) group.
