Using the released optical survey data, we searched for groups composed solely of dwarf galaxies, each with a stellar mass $M_*<10^{9.5}~M_{\\odot}$. We identified 14 dwarf galaxy groups with at least 5 dwarf galaxies, all located within a projected radius of 200 kpc and with a line-of-sight velocity of $\\pm$300 km~s$^{-1}$. We checked photometric and imaging data and found that these 14 dwarf galaxy groups are solitary, with no neighboring mass","authors_text":"J. L. Han, Z. L. Wen, Z. S.
