We give the classification of all possible G-graphs for any small binary dihedral subgroup G in GL(2,C) and use this classification to give the combinatorial description of the special representations of G in terms of its maximal cyclic normal subgroup.
Comment: Final version. Major improvement in the exposition, statements and proofs from the previous version thanks to suggestions of the anonymous referee. To appear in Glasgow Mathematical Journal
