Abstract: We describe an example of a $ {C^{\infty}}$ diffeomorphism on a 7-manifold which has a compact invariant set such that uncountably many of its connected components are pseudocircles. (Any 7-manifold will suffice.) Furthermore, any diffeomorphism which is sufficiently close (in the $ {C^1}$ metric) to the constructed map has a similar invariant set, and the dynamics of the map on the invariant set are chaotic.
