Obviously for a hexagonal system the c-axis is a very high symmetry <br>
direction. This corresponds to 0 0 1<br>
<br>
Of course, the a (or b) direction is also a special direction, but it <br>
will break hexagonal symmetry as the a and b directions will no longer <br>
be equivalent. So when you choose 1 0 0, in many cases the symmetry will <br>
be automatically reduced by symmetso.<br>
