The one- and two-step mechanisms of the pd→3HΛK+ reaction in the range of incident proton kinetic energy 1.13-3.0 GeV have been investigated. A remarkable peculiarity of the two-step mechanism which incorporates subprocesses pp→dπ+ and π+n→K+Λ is the so called velocity matching providing the presence of all intermediate particles nearly to the on-mass-shell. The differential cross section has been calculated using a realistic model for the hypertritium 3HΛ wave function. The maximum value of the cross section is estimated as ∼1nb/sr. The contribution of the one-step mechanism with the elementary process pN→NKΛ into the cross section has been found to be two - three orders of magnitude smaller in comparison with the two-step mechanism.
