60.39 PointGroup for color CrystGroups

If C is a color CrystGroup whose color subgroup is lattice-equal (or translationengleich) with C, the point group of C can consistently be colored. In that case,

PointGroup( C )

returns a colored point group. Otherwise, the point group will be uncolored. An uncolored point group can always be obtained with

C.operations.UncoloredPointGroup( C )
