Abstract
In this paper we discuss automorphism groups of saturated models and boundedly saturated models of . We show that there are saturated models of of the same cardinality with nonisomorphic automorphism groups. We then show that every saturated model of has short saturated elementary cuts with nonisomorphic automorphism groups.
