The automorphism groups of linear codes and canonical representatives of their semilinear isometry classes
Department of Mathematics, University of Bayreuth, 95440 Bayreuth, Germany
The algorithm is based on the partitioning and refinement idea which is also used to calculate the canonical labeling of a graph  and it similarly returns the automorphism group of the given linear code. The time needed by the implementation of the algorithm is comparable to Leon's program  for the calculation of the linear automorphism group of a linear code, but it additionally provides a unique representative and the automorphism group with respect to the more general notion of semilinear equivalence. The program can be used online under http://www.algorithm.uni-bayreuth.de/en/research/Coding_Theory/CanonicalForm/index.html.
