## Abstract The massless ϕ^4^ theory in four Euclidean dimensions is shown not to have a multiple‐instanton solution — even though it does have a single‐instanton solution. Our criterion for a multiple‐instanton solution of this nontopological theory is that the energy‐momentum tensor of the soluti
