We study invariant metrics on Ledger-Obata spaces F m / diag(F ). We give the classification and an explicit construction of all naturally reductive metrics, and also show that in the case m = 3, any invariant metric is naturally reductive. We prove that a Ledger-Obata space is a geodesic orbit space if and only if the metric is naturally reductive. We then show that a Ledger-Obata space is reducible if and only if it is isometric to the product of Ledger-Obata spaces (and give an effective method of recognising reducible metrics), and that the full connected isometry group of an irreducible Ledger-Obata space F m / diag(F ) is F m . We deduce that a Ledger-Obata space is a geodesic orbit manifold if and only if it is the product of naturally reductive Ledger-Obata spaces.2010 Mathematics Subject Classification. 53C30, 53C25, 17B20.
