First, note that, by the isomorphism between linear groups over field:F2, we have:
Here, PSL(3,2) stands for the projective special linear group of degree three over field:F2. stands for the projective general linear group of degree three, stands for the special linear group of degree three, and stands for the general linear group of degree three.
