Abstract

Two concepts of automorphism of a hypergroupoid are introduced; the first one preserve the algebraic structure of a hypergroupoid, the second one preserve the geometric structure that one can associate naturally to a hypergroupoid. The groups of such automorphisms are studied, in particular in the case that the geometric space associated to a hypergroupoid is a Steiner system.
