Query: Modelling questions for transitive quantum groups   This is a survey on the transitive quantum groups $G\subset S_N^+$, and on
the flat matrix models $\pi:C(G)\to M_N(C(X))$ for the corresponding Hopf
algebras. We review the known results on the subject, with a number of
improvements, technical generalizations, and some new results as well, and we
discuss the open problems.
