This paper is one of the first to give a systemic list of all modular tensor categories of low rank, and is used as a very common reference for researchers in the field. Since this paper, there have been various other numerical searches which classify modular tensor categories of low rank:

> Alekseyev, Max A., et al. "Classification of modular data of integral modular fusion categories up to rank 11." arXiv preprint arXiv:2302.01613 (2023).

Similar numerical searches have been done in other settings, such as fusion categories. It is very useful to have a conception of what small rank examples exist, for a medley of reasons. One nice theme of these papers is that they also highlight some of the most important and non-trivial features of modular tensor categories. In particular, these papers often exploit the implicit number theory lying in the pentagon and hexagon equations.

The fact that a rank-by-rank classification of MTCs is possible follows from the rank finiteness theorem:
