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..-->..bb-barX)B(bb-bar..--> 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..UPSILONX) B(UPSILON..--> mu../sup +/..mu../sup -/) <22 x 10/sup -39/ cm/sup 2/. In addition, analysis of 71 rare multimuon events, including four- and five-muon final states, is presented.
