NGC 3109 is the dominating member of a small group of dwarf galaxies, all of them Local Group member candidates, which also contains Sextans A, Sextans B, the Antlia Dwarf and perhaps Leo A.
It is still not finally clear if these galaxies are gravitationally bound to the Local Group of Galaxies, thus forming a subgroup of the Local Group, or if this is the nearest independent small group of galaxies.
