We show that for the $(N,Δ)$ part such a generalization is plausible allowing the identification of spectral regularities and the prediction of until now non-identified resonances.4 pages, Talk given at the 18th International Conference on Few-Body Problems in Physics, August 21-26 2006, Santos, Sao Paulo, BrazilHigh Energy Physics - Phenomenologytext
