Original Kurzfassung:
We investigate when the clone of congruence preserving functions is finitely generated. We obtain a full description for
all finite $p$-groups, and for all finite algebras with Mal'cev term and simple congruence lattice. The characterization for $p$-groups
allows a generalization to a large class of expansions of groups.
