AB - We study equivalences for category $\mathcal {O}_p$ of the rational Cherednik algebras $\textbf {H}_p$ of type $G_{\ell }(n) = (\mu _{\ell })^n\rtimes \mathfrak {S}_n$: a highest weight equivalence between $\mathcal {O}_p$ and $\mathcal {O}_{\sigma (p)}$ for $\sigma \in \mathfrak {S}_{\ell }$ and an action of $\mathfrak {S}_{\ell }$ on an explicit non-empty Zariski open set of parameters $p$; a derived equivalence between $\mathcal {O}_p$ and $\mathcal {O}_{p^{\prime }}$ whenever $p$ and $p^{\prime }$ have integral difference; a highest weight equivalence between $\mathcal {O}_p$ and a parabolic category $\mathcal {O}$ for the general linear group, under a non-rationality assumption on the parameter $p$. As a consequence, we confirm special cases of conjectures of Etingof and of Rouquier.
