Abstract

For a finite set X and the prower set $PX$ of X, we definite normal subsets of $PX$. We then describe all order-automorphisms of a normal subset of $PX$, and, in particular, characterize those normal subsets of $PX$ for which each order-automorphism is induced, i. e. determined by a permutation of X.
