  The large neutrino mixing angles have generated interest in finite subgroups
of SU(3), as clues towards understanding the flavor structure of the Standard
Model. In this work, we study the mathematical structure of the simplest
non-Abelian subgroup, Delta(3n^2). Using simple mathematical techniques, we
derive its conjugacy classes, character table, build its irreducible
representations, their Kronecker products, and its invariants.
