VV 166, sometimes also called the NGC 70 galaxy group or Arp 113, is a cluster of galaxies in Andromeda.

The main group was discovered in 1784 by William Herschel, who listed the galaxies as a single object.

Later, in the 1880s, John Louis Emil Dreyer managed to discern some of the galaxies in this region and cataloged them.

[2] The prominent elliptical galaxy in the region, NGC 68, is probably not a member of the group.

Superimposed on the group is a smaller cluster around 220 mly away, which includes AGC 102760, UGC 152, and UGC 166.
