Z2-Triple cyclic codes and their duals
A Z2-triple cyclic code of block length (r,s,t) is a binary code of length r+s+t such that the code is partitioned into three parts of lengthsr,s andt such that each of the three parts is invariant under the cyclic shifts of the coordinates. Such a code can be viewed as Z2[x]-submodules of Z_2[x]/ xZ_2[x]/ xZ_2[x]/ , in polynomial representation. In this paper, we determine the structure of these codes. We have obtained the form of the generators for such codes. Further, a minimal generating set for such a code is obtained. Also, we study the structure of the duals of these codes via the generators of the codes.
