Based on a data sample of (448.1 +/- 2.9) x 10(6) psi(3686) events collected with the BESIII detector at the BEPCII collider, the branching fraction of psi(3686) -> Lambda(Lambda) over bar omega is measured to be (3.30 +/- 0.34(stat) +/- 0.29(syst)) x 10(-5) for the first time. In addition, the Lambda omega (or (Lambda) over bar omega) invariant mass spectra is studied and the potential presence of excited. states has been investigated.
