<p><font size="-1">There is no problem. The code is doing what
expected. It is the input that is not one would expect. You
have an hexagonal lattice and you should specify in input a
mesh with the same number of divisions along the two equivalent
directions. <br>
</font></p>
<p><font size="-1">The code checks that the set of k points you use
for the BZ sum has the same symmetry as the lattice and adds
those points which are needed make the set symmetric. <br>
</font></p>
<p><font size="-1">It then removes all k-points which are
equivalent because of the crystal symmetry. If the crystal
symmetry group is made by less transformations than the lattice
symmetry group then not all points added are removed and the
number of k-points may be significantly larger compared with
those of a mesh with symmetric divisions in the mesh. <br>
