Abstract:Towards the study of finite projective plane of prime order, the following result is proved in this paper. Let pgr be a projective plane of prime order p and let G be a collineation group of pgr. If p¦|G|, then either pgr is Desarguesian or the maximal maximal normal subgroup of G is not trivial. In particular, pgr is Desarguesian if G does not leave invariant any point or line.Partially supported by NSERC A8460.Partially supported by CNPq.
