[en] The Pendleton and Ross arguments that quark masses may be related by the infrared fixed points of the renorm-group equations are critically examined. All fixed points are found, and it is shown that the infrared stable point is symmetrical in quark masses and lies lower than the Pendleton and Ross solution. For the 6-quark model the top quark mass msub(t) > or approximately 70 GeV and the Higgs mass msub(H) > or approximately 51 GeV are obtained
