  In this note we discuss the classification of duality orbits of N = 8 gauged
supergravity models. Using tensor classifiers, we show that there is a
one-parameter family of inequivalent SO(8) gauged supergravity theories. We
briefly discuss the couplings of such models and show that, although the
maximally symmetric vacuum has the same quadratic spectrum, the supersymmetry
transformations, the couplings and the scalar potential are parameter
dependent. We also comment on the possible M-theory uplift and on the meaning
of the parameter for the dual gauge theories.
