A few other galaxies at the periphery may be associated with the group but may not be gravitationally bound.

[2][3] It is considered to be at an early stage of evolution in which galaxies are still falling into the group along filamentary structures.

NGC, IC, UGC, and PGC numbers have been used when possible to allow for easier referencing.

However, recent distance measurements to these and other galaxies in the same region of the sky show that NGC 55, NGC 300, and their companions may simply be foreground galaxies that are physically unassociated with the Sculptor Group.

[2] The galaxies NGC 24 and NGC 45 are located in the vicinity of the Sculptor Group, but are now considered background objects.
