Representation dimension of some finite groups

Abstract

For a finite group GG, the representation dimension is the smallest integer realizable as the degree of a complex faithful representation of GG. In this article, we compute representation dimension for some pp-groups, their direct products, and groups with certain conditions on nonlinear irreducible characters. We also make similar computations for the smallest integer realizable as the degree of an irreducible complex faithful representation of GG, if one exists. In the appendix, we present GAP codes to compute these numbers.
