Abstract: The group E 6 for grand unification is combined with the generation symmetrygroup SO3 x Z2. The coupling matrices in the Yukawa interaction areidentified with the vacuum expectation values of scalar flavons. The symmetricpart of this 3x3 coupling matrix can be identified with the known up-quarkhierarchy. The antisymmetric part is responsible for fermion mixings and CPviolation. Numerical fits with only few parameters reproduce quantitatively allknown fermion properties. The model predicts an inverted neutrino hierarchy, CPviolation properties as well as the 0v2beta decay parameter. It also predictsthat the masses of the two lightest of six `right handed- neutrinos lie in thelow TeV region.
