The spectrum of anomalous dimensions in large N, non-planar limits of N=4 sypersymmetric Yang-Mills theories are considered. Restricted Schur polynomials provide a useful basis for this study. We will argue that the action of the one loop dilatation operator on restricted Schur operators is largely determined by the su(2) R-symmetry algebra. Our results generalize existing studies, allowing a study of operators that are not ½-BPS or small deformations thereof. An application of this result would be to study operators whose dimensions grow like N². These operators are dual to new background spacetime geometries in the quantum gravity.
