high symmetry k-points



Dear all,
   I want to investigate the band structures of some transitional metals
 surfaces. There are some question: How to chose the special k-points for
 the different surfaces such as (111), (100) and (110) surface? Where to
 find the the coordinate of some high symmetry k-points such as M, S points?
   With best regards!
