Recently, the first nuclei to lie along an arc of regularity in the collective symmetry triangle were identified. These nuclei are predicted to display significantly more ordered spectra than their neighbors. The nuclei identified all lie in the rare earth region from A=156–180. Here we present the results of a search of all known nuclei from A=90–208 and have identified an additional set of such candidates for regular nuclei using a particular degeneracy condition as a signature.
