The work contains a detailed description of the location of symmetry elements in sets, corresponding to every rotational symmetry group 3/2, 3/4, 3/5. All these groups are described in a common coordinate system, which simplifies both finding group symmetry element directions as well as comparing these directions for elements of different groups. Every element of every group has a unique index, and numerous automatically computed summary tables will help finding the angle between directions of any two symmetry axes from any of the three mentioned symmetry groups.
