Abstract
Several of the interesting new relations in elementary particle physics discovered from the hypothesis of SU6 symmetry of strong interactions, are shown to follow from the less restrictive assumption of SU4 symmetry alone. Since isospin invariance is a much more closely obeyed symmetry than SU3, these relations may be the best tests for the validity of combining internal symmetries with spin.
