This paper reports that regarding electrons as anyons of index {alpha}{sub s} with {minus}(m + {alpha}{sub s}) flux quanta per particle, and letting the mean field of these fluxes cancel the external magnetic field B, the authors obtain the filling factor {nu} = 1/(m + {alpha}{sub s}), where m must be odd. Demanding the resulting system of anyons to exhibit anyon superconductivity, we obtain {alpha}{sub s} = {plus minus}(1 {minus} q/n) where q is odd, and n {gt} q is relatively prime to q. For q = 1 the authors recover a formula due to Jain, and resolve the mystery why, for a state with {nu} = n/(2pn {plus minus} 1) {lt} 1 he requires use of the statistical correlation of n filled Landau levels. For q = 3,5,..., we obtain the fractions 4/11, 4/13, 5/13, etc., which are missing from Jain's list. Thus this non-hierarchical approach to the non-1/m fractional quantum Hall effect has the strengths of Jain's composite-fermion approach, but not its (potential) weaknesses.
