  It was recently shown that string theory on $\mathrm{AdS}_3 \times
\mathrm{S}^3 \times \mathbb{T}^4$ with minimal NS-NS flux ($k = 1$) is exactly
dual to the symmetric orbifold of T4. Here we show that a similar statement
also holds for the $D_n$ orbifolds of these backgrounds that have $\mathcal{N}
= (2, 2)$ supersymmetry. In this case the CFT dual is the symmetric orbifold of
$\mathbb{T}^4/D_n$.
