Query: Invariant Einstein metrics on Ledger-Obata spaces   In this paper, we study invariant Einstein metrics on Ledger-Obata spaces
$F^m/\operatorname{diag}(F)$. In particular, we classify invariant Einstein
metrics on $F^4/\operatorname{diag}(F)$ and estimate the number of invariant
Einstein metrics on general Ledger-Obata spaces $F^{m}/\operatorname{diag}(F)$.
