We address the question as to why the ordering of O_<xy>-type quadrupole moment predominates that of T_<xyz> octupole moment at no applied field in CeB_6, in spite of the same coupling constant predicted. In the mean field approximation (MFA), the same results are obtained for the quadrupolar and the octupolar interactions. If we go beyond the MFA to apply the constant coupling approximation, it is shown that the ordering of O_<xy> is stabilized compared with that of T_<xyz> as far as each interaction is treated separately.
