This correspondence provides counterexamples to two frequently proposed conjectures concerning group codes for the Gaussian channel. It is shown 1) that a code for which the list of distances from codeword i to all other words is independent of i is not necessarily a group code, and 2) a group code of M words need not possess a transitive symmetry group of order M .
