Description

In this talk, I will explain that the (E_8)_1 WZW model has Haagerup symmetry H_3, and that gauging H_3 gives a c = 8 theory with Z(H_3) symmetry. In addition, I will suggest a relation to theories with H_3 symmetry at c = 2 and c = 6, complementing the discussion with new modular bootstrap results.
