Abstract

We compute the modular data (that is, the SS and TT matrices) for the centre of the extended Haagerup subfactor. The full structure (i.e. the associativity data, also known as 6-jj symbols or FF matrices) still appears to be inaccessible. Nevertheless, starting with just the number of simple objects and their dimensions (obtained by a combinatorial argument in arXiv:1404.3955) we find that it is surprisingly easy to leverage knowledge of the representation theory of SL(2,Z)SL (2, \mathbb Z) into a complete description of the modular data. We also investigate the possible character vectors associated with this modular data.
