Abstract: There has been recent interest in Stallings' Pregroups. (See [2] and [12].) This paper gives a survey of generalized pregroups. We also answer a question of Reinhold Baer [1] on pregroups and answer a generalization of this question for generalized pregroups.

Keywords: Pregroups, Kushner Axiom K. small cancellation.
