The classification of topological phases of matter in 2+1d is notoriously difficult. At a physical level, much of the difficulty lies in getting a handle on the braiding data of anyonic excitations as well in characterising the associativity data of the anyonic OPE (i.e., the so-called “F-symbols”). Recently there has been great progress in characterising anyon braiding. In this talk, I will describe progress toward constraining the associativity data.
