A  Z 2 -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 lengths   r  ,   s   and   t   such that each part is invariant  under the cyclic shifts of the coordinates. Such a code can be viewed as  Z 2 [  x  ]-submodules of Z_2[x]/ *                                                           Z_2[x]/                          *                         Z_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 codes is obtained. Also, we study the structure of the duals of these codes  via the generators of the codes.
