Description
The icosahedral (A5) group has been shown to be a viable family symmetry group for the leptons. To incorporate the quarks, it is highly advantageous to extend the group to its double cover, as in the case of tetrahedral (A4) symmetry. In this talk, we present the basic group theoretical tools for flavor model-building based on the binary icosahedral group, I'. Using these tools, we construct a model of the quark masses and mixings that yields many of the successful predictions of the well-known U(2) quark texture models.
