The estimated number of galaxy groups, given that there are 100 billion galaxies in the universe, is 100 to 200 billion.

Galaxies that travel together through space are called galaxy groups or galaxy clusters. These are systems of galaxies bound together by gravity.
Most galaxies, even our own, are found in groups or clusters. For example, the Local Group contains several galaxies including the Milky Way, Andromeda, and the Magellanic clouds.
We are part of the Local Group. The Local Group contains the Milky Way, two other major galaxies, and dozens of dwarf galaxies. The Local Groups is a group of galaxies which, as galaxies go, are close to us.
Elliptical galaxies may vary in shape form but are spherical or flattened disk-shaped galaxies (large groups of stars). See related link for a pictorial.
Some galaxies are bound together gravitationally into what is called Local Groups. Because of the gravitational attraction between them they are approaching each other.
Yes, a group of galaxies can contain hundreds of galaxies. These collections are known as galaxy groups or clusters, with galaxy clusters typically housing dozens to thousands of galaxies. The gravitational attraction among the galaxies allows them to remain bound together within these larger structures. This clustering plays a significant role in the study of cosmic evolution and large-scale structures in the universe.
The Virgo Supercluster contains over 100 galaxy groups and clusters, including the well-known Virgo Cluster. Estimates suggest that it harbors approximately 2,000 galaxies, although some sources propose that the total could be higher, potentially encompassing up to 3,000 galaxies when accounting for smaller groups and isolated galaxies. This supercluster is part of the larger Laniakea Supercluster, which includes our Milky Way galaxy.
