The reaction e+e−→ π+ π−π0η has been studied in the experiment with the SND detector at the VEPP-2000 e+ e− collider. The reaction proceeds via the four intermediate states: ωη, φη, a0ρ, and structureless π+π−π0η state, which may be, for example, ρ(1450) with ρ(1450) → ρ(770)η. The total e+e−→ π+π−π0η cross section and cross section for the four intermediate states have been measured and fitted in the vector meson dominance model.
