The algebra-object decomposition conjecture for the _1-_3 subfactor

Let NMN\subset M be the I1\mathscr{I}_1-I3\mathscr{I}_3 subfactor constructed above, and let γ\gamma be the corresponding algebra object in I1\mathscr{I}_1. Here νj\nu_j and μj\mu_j denote the simple objects indexed by jj, as in the fusion-category notation of the paper.

Algebra-object decomposition conjecture. The algebra object satisfies

γ1+j=1n12(νj+μj).\gamma\cong 1+\sum_{j=1}^{\frac{n-1}{2}}(\nu_j+\mu_j).

This conjecture identifies the algebra object associated with the constructed subfactor and would determine the corresponding principal-graph data. The paper states that it is verified in the cases n=3n=3 and n=5n=5, but cannot be verified for arbitrary nn.
