Abstract: Let $ G$ be the free abelian group with a countable number of generators. We construct a separable locally compact $ G$-transformation space $ X$ without closed minimal invariant subsets, such that the corresponding $ {C^ \ast }$-algebra $ {C^ \ast }(G,X)$ has the properties mentioned in the title. Using $ X$ we also give an example of a transformation space $ (G,Z)$ without closed minimal invariant subset, on which $ G$ acts freely.
