Recall that a subgroup $H$ of a group $G$ is called a *TI-subgroup*
if for every $g \in G$ one has $H \cap H^g \in \{1,H\}$.
We say that a group $G$ is a DTI-group if the derived subgroups of all
of its subgroups are TI-subgroups of $G$.

*Question:* Is the class of DTI-groups closed under taking quotients?
