N2 - Using a sample of (2.712 ±0.014)×109 휓(3686) events collected with the BESIII detector at the BEPCII collider in 2009, 2012, and 2021, the decay 휓(3686) →휔휂휂 is observed for the first time. The branching fraction of the 휓(3686) →휔휂휂 decay is measured to be (1.65 ±0.02 ±0.21)×10−5, where the first uncertainty is statistical and the second systematic.
