	abstract = {The space of solutions of the exact renormalization group fixed point equations of the two-dimensional <em>RP</em>ᴺ$^{-}${\textonesuperior} model, which we recently obtained within the scale invariant scattering framework, is explored for continuous values of <em>N</em> >= 0. Quasi-long-range order occurs only for <em>N</em> = 2, and allows for several lines of fixed points meeting at the Berezinskii-Kosterlitz-Thouless transition point. A rich pattern of fixed points is present below <em>N</em>* = 2.244 21. . , while only zero temperature criticality in the O(<em>N</em>(<em>N</em> + 1)/2 - 1) universality class can occur above this value. The interpretation of an extra solution at <em>N</em> = 3 requires the identification of a path to criticality specific to this value of <em>N</em>.},
