Modular Data

This fusion ring does not have any matching \(S\)-and \(T\)-matrices.

Adjoint Subring

Particles \(\mathbf{1}, \mathbf{2}, \mathbf{3}, \mathbf{4}, \mathbf{5}\), form the adjoint subring \(\left.\text{Rep(}D_4\right):\ \text{FR}^{5,0}_{1}\) .

The upper central series is the following: \(\text{FR}^{9,4}_{8} \underset{ \mathbf{1}, \mathbf{2}, \mathbf{3}, \mathbf{4}, \mathbf{5} }{\supset} \left.\text{Rep(}D_4\right) \underset{ \mathbf{1}, \mathbf{2}, \mathbf{3}, \mathbf{4} }{\supset} \mathbb{Z}_2\times \mathbb{Z}_2 \underset{ \mathbf{1} }{\supset} \text{Trivial}\)

Universal grading

Each particle can be graded as follows: \(\text{deg}(\mathbf{1}) = \mathbf{1}', \text{deg}(\mathbf{2}) = \mathbf{1}', \text{deg}(\mathbf{3}) = \mathbf{1}', \text{deg}(\mathbf{4}) = \mathbf{1}', \text{deg}(\mathbf{5}) = \mathbf{1}', \text{deg}(\mathbf{6}) = \mathbf{2}', \text{deg}(\mathbf{7}) = \mathbf{3}', \text{deg}(\mathbf{8}) = \mathbf{2}', \text{deg}(\mathbf{9}) = \mathbf{3}'\), where the degrees form the group \(\mathbb{Z}_3\) with multiplication table:

\[\begin{array}{|lll|} \hline \mathbf{1}' & \mathbf{2}' & \mathbf{3}' \\ \mathbf{2}' & \mathbf{3}' & \mathbf{1}' \\ \mathbf{3}' & \mathbf{1}' & \mathbf{2}' \\ \hline \end{array}\]
