        abstract = {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.}
