摘要

Over finite local Frobenius non-chain rings with nilpotency index 3 and when the length of the codes is relatively prime to the characteristic of the residue field of the ring, the structure of the dual of gamma-constacyclic codes is established and the algebraic characterization of self-dual gamma-constacyclic codes, reversible gamma-constacyclic codes and gamma-constacyclic codes with complementary dual are given. Generators for the dual code are obtained from those of the original constacyclic code. (C) 2019 Elsevier B.V. All rights reserved.
