Pulsating strings from two dimensional CFT on $(T^4{)}^N\mathrm{/}S(N)$

We propose a state from the two-dimensional conformal field theory on the orbifold $(T^4{)}^N\mathrm{/}S(N)$ as a dual description for a pulsating string moving in $Ad{S}_3$. We show that, up to first order in the deforming parameter, the energy in both descriptions has the same dependence on the mode number, but with a non-trivial function of the coupling.
