Let Cl(O K [G]) denote the locally free class group, that is the group of stable isomorphism classes of locally free O K [G]-modules, where O K is the ring of algebraic integers in the number field K and G is a finite group. We show how to compute the Swan subgroup, T (O K [G]), of Cl(O K [G]) when K = Q(ζp), ζp a primitive p-th root of unity, G = C 2 ,… (More)

The holomorph of a group G is N orm B (λ(G)), the normalizer of the left regular representation λ(G) in its group of permutations B = P erm(G). The multiple holomorph of G is the normalizer of the holomorph in B. The multiple holomorph and its quotient by the holomorph encodes a great deal of information about the holomorph itself and about the group λ(G)… (More)
