Strings on certain AdS3 space-times are described by integrable 2d sigma models on Z2 and Z4 permutation cosets with G x G symmetry group. The product structure of the symmetry group leads to a richer space of integrable deformations. In this talk I will outline recent progress in mapping out this space, before discussing a special class of deformations of AdS3 x S3 x T4 that preserve half the supersymmetry. Interestingly, these deformations can either be found via Yang-Baxter deformations, proving their integrability, or by U-duality transformations.
