Abstract

The symmetric orbifold of \mathbbT⁴ is the CFT dual of string theory on AdS₃× \rm S³ × \mathbbT⁴ with minimal NS-NS flux. We study its symmetry algebra and provide evidence that it does not have any deformation parameter. This suggests that the symmetric orbifold is (at least locally) the most symmetrical CFT in its moduli space.
