%X We consider the so-called ring Q-mappings, which are natural generalizations of quasiregular mappings  in a sense of V¨ais¨al¨a’s geometric definition of moduli. It is shown that, under the condition of nondegeneracy  of these mappings, their inner dilatation is majorized by a function Q.x/ to within a constant  depending solely on the dimension of the space.
