Use Young diagrams to obtain the SU(6) Clebsch-Gordan series \(\mathbf{6} \otimes \mathbf{6} \otimes \mathbf{6}=\mathbf{5 6} \oplus\) \(\mathbf{7 0} \oplus \mathbf{7 0} \oplus \mathbf{2 0}\) of Eq. (9.5) that is relevant for baryons, and the Clebsch-Gordan series \(\mathbf{6} \otimes \mathbf{6} \otimes \overline{\mathbf{6}}=\mathbf{3 5} \oplus \mathbf{1}\) of Eq. (9.7) that is relevant for mesons.
