Abstract: Groups act as symmetries of physical systems and on their mathematical models
- such as actions on algebras of operators on Hilbert spaces..
Symmetries beyond those arising from groups or their
deformations as quantum groups, loop groups are feasible but hard to locate and realise.
The accepted position was that the Haagerup system was exotic and surely could not be constructed from group like symmetries.
We discuss work with Terry Gannon that this should be considered as misconception and the more general issue of reconstructing
conformal field theories from modular tensor categories.
