A search for the production of events containing three W bosons predicted by the standard model is reported. The search is based on a data sample of proton-proton collisions at a center-of-mass energy of 13 TeV recorded by the CMS experiment at the CERN LHC and corresponding to a total integrated luminosity of 35.9 $\\mathrm{fb}^{\u22121}$. The search is performed in final states with three leptons (electrons or muons), or with two same-charge leptons plus two jets. The observed (expected) significance of the signal for $\\mathrm{W}^{\\pm}\\mathrm{W}^{\\pm}\\mathrm{W}^{\\mp}$ production is 0.60 (1.78) standard deviations, and the ratio of the measured signal yield to that expected from the standard model is $0.34^{+0.62}_{\u22120.34}. Limits are placed on three anomalous quartic gauge couplings and on the production of massive axion-like particles. \nThe two equally charged (SS) channel fiducial region is defined as\n- exactly 2e, 2mu or 1e1mu with both leptons having the same charge\n- ptLepton > 25 GeV\n- |etaLepton| < 2.4\n- the invariant mass of the two leptons has to be >40 (30) GeV for 2e or 2mu (emu) and |mll -
