Section 3 gives the <Standard Model> <branching rules> of the $SU(6)$ <representations> $\overline{\mathbf6}$ and $\mathbf{15}$. Their cubic <gauge anomaly> coefficients are $-1$ and $2$, respectively; one $\mathbf{15}$ with two $\overline{\mathbf6}$ therefore cancels this <gauge anomaly>. Additional charged <fermions> can form a <vectorlike gauge spectrum> with invariant mass terms.
