Quantum subgroups of simple twisted quantum groups at roots of one

Let $G$ be a connected, simply connected simple complex algebraic group and let $ϵ$ be a primitive $\mathrm{\ell }$th root of unity with $\mathrm{\ell }$ odd and coprime with $3$ if $G$ is of type $G_2$. We determine all Hopf algebra quotients of the twisted multiparameter quantum function algebra ${\mathcal{O}}_{ϵ}^{\phi }(G)$ introduced by Costantini and Varagnolo. This extends the results of Andruskiewitsch and the first author, where the untwisted case is treated.
