    32 point group system "mmm" in Orthorhombic crystal

    I am trying to understand the mmm symmetry in a orthorhombic crystal. Looking from the diagram I know there are 5 diads which will give me 10 unique planes in the same form. But how do I know the exact planes that are in the form given one of them (lets say, 210)

    You need the coordinates of the atoms.
