hexagonal symmetry points

saray1360

Dear all,

It is trivial, but please let me know how I can clculate high symmetry points for hexagonal lattice. I know the points are gamma, A, H , L, M and K but I do not know how to calculate them. For example I have a k-point grid in reciprocal lattice as follows:

7.0 0.0 0.0
0.0 7.0 0.0
0.0 0.0 5.0

Please do help me, it is really urgent for me.

Regards,
sara
