The table below summarizes the maximal degree M of extremal unpolarized, pure states with N photons (or, equivalently, spin S=N/2). For those states, all multipoles up to order M vanishes, corresponding to isotropic moments of the Stoke's variables up to Mth order. Furthermore, the cumulative squared lengths A(S)M vanishes.
So far, in all case for which we have found solutions, the maximal degree M of unpolarization matches the largest degree t for which a spherical t design with N points is known to exist.
