  "abstract": "The cross section of the process $e^+e^- \\to π^+π^-π^0π^0η$ has been measured using a data sample with the integrated luminosity of 372 pb$^{-1}$ collected with the CMD-3 detector at the VEPP-2000 $e^+e^-$ collider. 6300$\\pm$145 signal events have been selected in the center-of-mass energy range 1.6--2.0 GeV. The total systematic uncertainty of the cross section is about 10\\%. The production dynamics is dominated by the $ω(782)π^0η$ final state with a possible small contribution of the $a_0(980)$ resonance in the $π^0η$ combination. We also observe a presence of the $ρ(770)^{\\pm}$ resonance signal in the $π^{\\pm}π^0$ invariant mass distribution.",
