Our project is to introduce the updated database of Z4 codes. We added codes to the database that have been found through exhaustive searches on cyclic codes and by an implementation of the ASR search algorithm, which has been remarkably fruitful to obtain new linear codes from the class of quasi-cyclic (QC) and quasi-twisted (QT) codes over finite fields. We made modifications to the ASR algorithm to make it work over ℤ4.
