N2 - The results of the search for the e+e-→η′γ process in the center-of-mass energy range from 1.075 to 2 GeV are presented. We analyze data with an integral luminosity of 746 pb-1 accumulated with the SND detector at the e+e- collider VEPP-2000 in 2010-2024. The η′→ηπ0π0 decay is used in the analysis, with the subsequent η and π0 decays into γγ. Upper limits not exceeding 13 pb have been set on the e+e-→η′γ cross section at the 90% confidence level.
