A search for the neutrinoless, lepton-flavor violating decay of the tau lepton into three charged leptons has been performed using an integrated luminosity of 468 fb^-1 collected with the BABAR detector at the PEP-II collider. In all six decay modes considered, the numbers of events found in data are compatible with the background expectations. Upper limits on the branching fractions are set in the range (1.8-3.3) X 10^-8 at 90% confidence level.

Belle II sets upper limits between 1.3 and 2.5 times 10 to the minus 8 on branching fractions for four tau to e l l decay modes at 90 percent confidence level, the most stringent to date for four modes.
