| Abstract: | In this paper we extend the notion of an incidence group to that of a groupoid. The concept of near-algebras, introduced below, enables us to describe Desarguesian incidence groupoids algebraically and to generalize most of the essential results about projective incidence groups with regard to groupoids.
