I will explain various pieces of evidence in favour of an exact duality relating string theory on AdS3 x S3 x T4 with minimal NSNS flux (k=1) to the symmetric orbifold of T4. In particular, I shall demonstrate that the spectrum matches exactly, and I shall outline first results indicating that the structure of correlation functions of the symmetric orbifold is exactly reproduced from the world-sheet. (This is based on work, partially in progress, with Lorenz Eberhardt and Rajesh Gopakumar.)
