This program gives access to the relation between the irreducible
representations (only for the Γ point) of point groups which
are group-subgroup related. In that way one can study the behaviour
of IR, Raman and Hyper-Raman active modes in a group-subgroup pairs.
One have to choose one of the point groups of the table and the
subgroups of the chosen group will be in the next step of the program.
Before one have selected the subgroup the information about the
relation between the irreducible representation will be shown.
