We classify completely all irreducible representations of the Poincaré Group (including inversions) corresponding to positive or zero mass systems, using a generalized version of the method of VARADARAJAN [9] which seems to be more convenient for practical computation than the method of PARTHASARATHY [5]. The case of zero mass — infinite helicity systems which was not considered previously in the literature is treated in a complete fashion.
