We close a gap in previous studies of nonsupersymmetric N = 0 quiver gauge theories from a phenomenological point of view aimed at acquiring specific proposals for models beyond the Standard Model (BSM). Because SU(3) is the gauge group of QCD we fix N = 3 and vary only the Z(p) abelian orbifold. The values 1 <= p <= 7 have been previously fully discussed as well as one special case, discovered by happenstance, of p = 12. The values p = 8 and p = 9 are discussed comprehensively in the present paper including the electroweak mixing angle, gauge coupling unification, spontaneous symmetry breakdown to the standard model, and the occurrence of three quark-lepton families. Two promising quiver node identifications are discovered for p = 8 and three for p = 9. All of these merit further study as BSM candidates. (C) 2017 The Author(s). Published by Elsevier B.V.
