We observe enhanced three-body recombination in an ultracold three-component$^6$Li Fermi gas with large but unequal scattering lengths attributable to anexcited Efimov trimer state near the three-atom scattering threshold. We findexcellent agreement between the measured three-body recombination rate and therecombination rate calculated in the zero-range approximation where the onlyfree parameters are the Efimov parameters $\kappa_*$ and $\eta_*$. The value of$\kappa_*$ determined by the location of the Efimov resonance we observe at 895G also predicts the locations of loss features previously observed near 130 and500 G \cite{Jochim08,OHara09} suggesting that all three features are associatedwith universal Efimov trimer states. We also report on the first realization ofa quantum degenerate three-state Fermi gas with approximate SU(3) symmetry.
