Analysis of dimuon final states from 1.4×1011 positive and 2.9×1010 negative 209-GeV muons in a magnetized iron calorimeter has set a lower limit of 9 GeV/c2 on the mass of a heavy neutral muon (M0), and a 90%-confidence-level upper limit of f(Nbb»X)B (bb»X)<2. 9×10-36 cm2 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 states: f(NX) (+-) <22×10-39 cm2. In addition, analysis of 71 rare multimuon events, including four- and five-muon final states, is presented.
