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 limit of sigma(..mu..N ..-->.. b anti b X)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 three muon final states places a 90%-confidence level limit for the muon production 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.
