Query: Regular irreducible represntations of classical groups over finite
  quotient rings   A parametrization of irreducible representations associated with a regular
adjoint orbit of a classical group over finite quotient rings of the ring of
integer of a non-dyadic non-archimedean local field is presented. The
parametrization is given by means of (a subset of) the character group of the
centralizer of a representative of the regular adjoint orbit. Our method is
based upon Weil representations over finite fields. More explicit
parametrization in terms of tamely ramified extensions of the base field is
given for the general linear group, the special linear group, the symplectic
group and the orthogonal group.
