  In this paper, we discuss O-basis of symmetry classes of polynomials
associated with the Brauer character of the Semi-Dihedral groups and Dihedral
groups. Also, necessary and sufficient conditions are given for the existence
of an orthogonal basis consisting of standard (decomposable) symmetrized
tensors for the class of tensors symmetrized using a Brauer character of the
Semi-Dihedral groups.
