摘要：
Recently, Jia proposed the decompositions and trace representations of quasi-twisted (QT) codes over finite fields (Finite Fields Appl 18:237–257, 2012). The present paper can be viewed as a complementary part of Jia’s work. We investigate some other useful properties of (Formula Presented.)-QT codes over finite fields, including the lower Hamming distance bounds, enumerations and searching algorithm for generators. As an interesting application of (Formula Presented.)-QT codes over finite fields, we study (Formula Presented.)-QT codes over the finite non-chain ring (Formula Presented.) briefly. © 2014, Korean Society for Computational and Applied Mathematics.
