Modular Data

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

Adjoint Subring

Particles \(\mathbf{1}, \mathbf{2}, \mathbf{5}, \mathbf{6}\), form the adjoint subring \(\text{PSU(2})_6:\ \text{FR}^{4,0}_{4}\) .

The upper central series is the following: \(\text{FR}^{8,4}_{12} \underset{ \mathbf{1}, \mathbf{2}, \mathbf{5}, \mathbf{6} }{\supset} \text{PSU(2})_6\)

Universal grading

Each particle can be graded as follows: \(\text{deg}(\mathbf{1}) = \mathbf{1}', \text{deg}(\mathbf{2}) = \mathbf{1}', \text{deg}(\mathbf{3}) = \mathbf{2}', \text{deg}(\mathbf{4}) = \mathbf{2}', \text{deg}(\mathbf{5}) = \mathbf{1}', \text{deg}(\mathbf{6}) = \mathbf{1}', \text{deg}(\mathbf{7}) = \mathbf{2}', \text{deg}(\mathbf{8}) = \mathbf{2}'\), where the degrees form the group \(\mathbb{Z}_2\) with multiplication table:

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