초록

The classification of the self-dual codes over Galois rings $GR(p,2)$ and $GR(p^2,2)$ of length 4 is completed for all primes $p$ up to equivalence in terms of automorphism group. We obtain all inequivalent classes and the number of each classes of self-dual codes for all primes.

Abstract

The classification of the self-dual codes over Galois rings $GR(p,2)$ and $GR(p^2,2)$ of length 4 is completed for all primes $p$ up to equivalence in terms of automorphism group. We obtain all inequivalent classes and the number of each classes of self-dual codes for all primes.
