This group contains between 8 and 24 galaxies, including three Messier objects.

The group is one of many groups that lies within the Virgo Supercluster (the combined Local Group and Virgo cluster).

[7] The table below lists galaxies that have been consistently identified as group members in the Nearby Galaxies Catalog,[5] the survey of Fouque et al.,[6] the Lyons Groups of Galaxies (LGG) Catalog,[3] and the three group lists created from the Nearby Optical Galaxy sample of Giuricin et al.[4] The Leo Triplet, which includes the spiral galaxies M65, M66, and NGC 3628,[3][4][5] is located physically near the M96 Group.

[10] Some group identification algorithms actually identify the Leo Triplet at part of the M96 Group.

[4][6] The two groups may actually be separate parts of a much larger group.
