Fusion Rules

$\begin{array}{|lllll|} \hline \mathbf{1} & \mathbf{2} & \mathbf{3} & \mathbf{4} & \mathbf{5} \\ \mathbf{2} & \mathbf{1} & \mathbf{4} & \mathbf{3} & \mathbf{5} \\ \mathbf{3} & \mathbf{4} & \mathbf{2}+\mathbf{5} & \mathbf{1}+\mathbf{5} & \mathbf{3}+\mathbf{4} \\ \mathbf{4} & \mathbf{3} & \mathbf{1}+\mathbf{5} & \mathbf{2}+\mathbf{5} & \mathbf{3}+\mathbf{4} \\ \mathbf{5} & \mathbf{5} & \mathbf{3}+\mathbf{4} & \mathbf{3}+\mathbf{4} & \mathbf{1}+\mathbf{2}+\mathbf{5} \\ \hline \end{array}$

The fusion rules are invariant under the group generated by the following permutations:

$\{(\mathbf{3} \ \mathbf{4})\}$

The following particles form non-trivial sub fusion rings

Particles	SubRing
$\{\mathbf{1},\mathbf{2}\}$	$\mathbb{Z}_2:\ \text{FR}^{2,0}_{1}$
$\{\mathbf{1},\mathbf{2},\mathbf{5}\}$	$\left.\text{Rep(}D_3\right):\ \text{FR}^{3,0}_{2}$

Quantum Dimensions

Particle	Numeric	Symbolic
$\mathbf{1}$	$1.$	$1$
$\mathbf{2}$	$1.$	$1$
$\mathbf{3}$	$1.73205$	$\sqrt{3}$

Characters

The symbolic character table is the following

$\begin{array}{|ccccc|} \hline \mathbf{1} & \mathbf{2} & \mathbf{3} & \mathbf{4} & \mathbf{5} \\ \hline 1 & 1 & \sqrt{3} & \sqrt{3} & 2 \\ 1 & 1 & 0 & 0 & -1 \\ 1 & 1 & -\sqrt{3} & -\sqrt{3} & 2 \\ 1 & -1 & i & -i & 0 \\ 1 & -1 & -i & i & 0 \\ \hline \end{array}$

The numeric character table is the following

$\begin{array}{|rrrrr|} \hline \mathbf{1} & \mathbf{2} & \mathbf{3} & \mathbf{4} & \mathbf{5} \\ \hline 1.000 & 1.000 & 1.732 & 1.732 & 2.000 \\ 1.000 & 1.000 & 0 & 0 & -1.000 \\ 1.000 & 1.000 & -1.732 & -1.732 & 2.000 \\ 1.000 & -1.000 & 1.000 i & -1.000 i & 0 \\ 1.000 & -1.000 & -1.000 i & 1.000 i & 0 \\ \hline \end{array}$

Modular Data

This fusion ring does not have any matching $S$-and $T$-matrices.

Adjoint Subring

Particles $\mathbf{1}, \mathbf{2}, \mathbf{5}$, form the adjoint subring $\left.\text{Rep(}D_3\right):\ \text{FR}^{3,0}_{2}$ .

The upper central series is the following: $\text{Pseudo SU(2})_4 \underset{ \mathbf{1}, \mathbf{2}, \mathbf{5} }{\supset} \left.\text{Rep(}D_3\right)$

Universal grading

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

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