Abstract. I will begin by defining a prism manifold M and the two ways that such a manifold can be S1-fibered. These manifolds have an imbeddded Heegaard Klein bottle. We consider the classification, up to equivalence, of all finite group actions which operate on M and preserve a Heegaard Klein bottle K. These actions are completely determined by their restrictions to K, and any such action is found to be isomorphic to either Zm, Z2 ×Z2m, Dih(Zm) or Dih(Z2 ×Z2m). In addition, we will consider fiber-preserving actions and the question of when such actions leave a Heegaard Klein bottle invariant.
