The value of this characteristic is alpha_137(29*137) = 0.007297352532... . The complementary characteristic alpha_29(29*137)=0.034280626357... for the cyclic subgroup of order 29 is shown to represent the gauge theory electro-weak coupling quantity g^2/(4 pi). Kinematic aspects of the representation geometry are discussed and a generalized version of the Weinberg electro-weak mixing angle is introduced.8 pagesQuantum Physicstext
