NGC 3753 is a member of the Copeland Septet which consists of 7 galaxies discovered by Copeland in 1874.[5] The other members are NGC 3746, NGC 3745, NGC 3748, NGC 3750, NGC 3751 and NGC 3754.[6]

Halton Arp noticed the 7 galaxies in the group, in which he published the article in 1966.[7] The group is designated as Arp 320 along another galaxy, PGC 36010.[8]

This group was observed by Paul Hickson in which he included them in his article in 1982.[9] The group is known as Hickson 57 in which NGC 3753 is the dominant member.[10]
