      abstract     = {We study the marginal deformation of the symmetric-product
                      orbifold theory Sym$_N(T^4)$ which corresponds to
                      introducing a small amount of Ramond-Ramond flux into the
                      dual $AdS_3\times S^3\times T^4$ background. Already at
                      first order in perturbation theory, the dimension of certain
                      single-cycle operators is corrected, indicating that
                      wrapping corrections from integrability must come into play
                      earlier than expected.We also discuss a flaw in the original
                      derivation of the integrable structure of the perturbed
                      orbifold.Together, these observations suggest that more
                      needs to be done to correctly identify and exploit the
                      integrable structure of the perturbed orbifold CFT.},
