Clifford-Weil groups for finite group rings, some examples.

A. Gunther, G. Nebe


Finite group rings carry a natural involution that defines a form ring structure. We investigate the associated Clifford-Weil groups for the indecomposable representations of the groups of order $2,3$ and the symmetric group $\Sym_3$ over the fields with 2 and 3 elements as well as suitable symmetrizations. An analogue of Kneser's neighboring method is introduced, to classify all self-dual codes in a given representation.
