Similar to the solution above, but with one polar and one equatorial circlet rather than two polar circlets. The down quarks all reside at the equator and the pole opposite the one shown. (Side and opposite pole not shown because I never bothered to actually build the model.) This neutron shell will stack with P535P to form a Boron 11 nuclei having all 5 of the proton shells P.V.B.'s clustered at one pole of the P535P shell. It will also stack into complementary shells with P630PA to form a highly polarized nuclear isomer of carbon 12.
