Adjoint Subring
Particles \(\mathbf{1}, \mathbf{2}, \mathbf{7}\), form the adjoint subring \(\left.\text{Rep(}D_3\right):\ \text{FR}^{3,0}_{2}\) .
The upper central series is the following: \(\text{Rep(}D_3\text{)$\times $}\mathbb{Z}_3 \underset{ \mathbf{1}, \mathbf{2}, \mathbf{7} }{\supset} \left.\text{Rep(}D_3\right)\)
Universal grading
Each particle can be graded as follows: \(\text{deg}(\mathbf{1}) = \mathbf{1}', \text{deg}(\mathbf{2}) = \mathbf{1}', \text{deg}(\mathbf{3}) = \mathbf{2}', \text{deg}(\mathbf{4}) = \mathbf{3}', \text{deg}(\mathbf{5}) = \mathbf{3}', \text{deg}(\mathbf{6}) = \mathbf{2}', \text{deg}(\mathbf{7}) = \mathbf{1}', \text{deg}(\mathbf{8}) = \mathbf{2}', \text{deg}(\mathbf{9}) = \mathbf{3}'\), where the degrees form the group \(\mathbb{Z}_3\) with multiplication table:
\[\begin{array}{|lll|} \hline \mathbf{1}' & \mathbf{2}' & \mathbf{3}' \\ \mathbf{2}' & \mathbf{3}' & \mathbf{1}' \\ \mathbf{3}' & \mathbf{1}' & \mathbf{2}' \\ \hline \end{array}\]Categorifications
