Abstract
We have searched for the decay of the tau lepton into seven charged pa rticles and zero or one pi(0). The data used in the search were collec ted with the CLEO II detector at the Cornell Electron Storage Ring (CE SR) and correspond to an integrated luminosity of 4.61 fb(-1). No evid ence for a signal is found. Assuming all the charged particles are pio ns, we set an upper limit on the branching fraction B(tau(-)-->4 pi(-) 3 pi(+)(pi(0)) nu(tau))<2.4 x 10(-6) at the 90% confidence level. This limit represents a significant improvement over the previous limit.
