Abstract

The smallest known example of a family of modular categories that is not determined by its modular data are the rank 49 categories Z(VecGω)\mathcal{Z}(\text{Vec}_G^{\omega}) for G=Z11Z5G=\mathbb{Z}_{11} \rtimes \mathbb{Z}_{5}. However, these categories can be distinguished with the addition of a matrix of invariants called the WW-matrix that contains intrinsic information about punctured SS-matrices. Here we show that it is a common occurrence for knot and link invariants to carry more information than the modular data. We present the results of a systematic investigation of the invariants for small knots and links. We find many small knots and links that are complete invariants of the Z(VecGω)\mathcal{Z}(\text{Vec}_G^{\omega}) when G=Z11Z5G=\mathbb{Z}_{11} \rtimes \mathbb{Z}_{5}, including the 525_2 knot.
