By analyzing $(448.1\ifmmode\pm\else\textpm\fi{}2.9)\ifmmode\times\else\texttimes\fi{}{10}^{6}\text{ }\text{ }\ensuremath{\psi}(3686)$ events collected with the BESIII detector operating at the BEPCII collider, the decays of ${\ensuremath{\chi}}_{cJ}\ensuremath{\rightarrow}\mathrm{\ensuremath{\Lambda}}\overline{\mathrm{\ensuremath{\Lambda}}}\ensuremath{\eta}$ ($J=0$, 1, and 2) are observed for the first time with statistical significances of $13.9\ensuremath{\sigma}$, $6.7\ensuremath{\sigma}$, and $8.2\ensuremath{\sigma}$, respectively. The product branching …
