Analysis of dimuon final states from 1.4 x 10/sup 11/ positive and 2.9 x 10/sup 10/ negative 209-Gev muons in a magnetized iron calorimeter has set a lower limit of 9 Gev/c/sup 2/ on the mass of a heavy neutral muon (M/sup 0/), and a 90%-confidence level upper limit of sigma(..mu..N..-->..b anti bX)B(b anti b..--> mu..X)<2.9 x 10/sup -36/ cm/sup 2/ for the production of bottom hadrons by muons. The dimuon mass spectrum from 102,678 trimuon final states places a 90%-confidence level upper limit for the muoproduction of upsilon states: sigma(..mu..N..--> mu.. UPSILON X)B(UPSILON..--> mu../sup +/..mu../sup -/)<22 x 10/sup -39/ cm/sup 2/. In addition, analysis of 71 rare multimuon events, including 4- and 5-muon final states, is presented.
