Abstract In this paper, we first prove that for each continuum Z Z, the class of all hereditarily indecomposable continua YZ Y Z that map onto Z Z by a light map does not admit a common model. Also, for several topological properties previously shown not to be Whitney reversible, we demonstrate that the corresponding classes of continua forming the counterexamples do not admit a common model.
