Halton Arp noticed the group when he published the article in 1966.[8] The group is designated as Arp 320 in which another galaxy PGC 36010, is part of it.[9]

This group was also observed by Paul Hickson, in which he included them inside his article in 1982.[10] This group is known as Hickson 57, in which NGC 3745 is designated as HCG 57G.[11]
