Automorphism Group

AutomorphismGroup(C): CodeAdd -> GrpPerm

The automorphism group of the additive code \(C\). Currently, this function is only available for additive codes over \(GF(4)\).

PermutationGroup(C): CodeAdd -> GrpPerm

The subgroup of the automorphism group of the additive code \(C\) consisting of permutations of the coordinates. Currently, this function is only available for additive codes over \(GF(4)\).
