Query: Finite generation of congruence preserving functions   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.
