Our own Local Group of galaxies contains just three large galaxies and several dozen small ones. Although this is typical, there are many clusters that contain far more galaxies. The nearest rich cluster is the Virgo cluster which contains at least 150 large galaxies and thousands of small ones. This cluster dominates the surrounding space and most of the neighbouring groups are gravitationally influenced by it. This region of space is known as the Virgo supercluster. Superclusters are the largest structures in the Universe.
This is a list of galaxy groups within 100 million light years according to P Fouqué and co-workers. Most distances are from the Nearby Galaxies Catalogue. All of these groups are ones containing at least 3 galaxies with an angular diameter larger than 100 arcseconds - a measure which is obviously biased towards closer groups. There are over a thousand galaxies in this list scattered among 148 groups, but by no means are all large galaxies included, many other galaxies are perhaps only loosely bound to a group, and hence are not included or they belong to a group without a sufficient number of large galaxies to make it onto the list. It is very rare however for a galaxy to be completely isolated in space.

Column 1: Name of the group. Usually the catalog number of the brightest
galaxy, or the name of the constellation in which the group lies.
Column 2: The Right Ascension in hours and minutes for epoch 2000.
Column 3: The declination in degrees for epoch 2000.
Column 4: The supergalactic longitude.
Column 5: The supergalactic latitude.
Column 6: The number of galaxies in the group with an angular diameter
larger than 100 arcseconds
Column 7: The recessional velocity of the group relative to the cosmic
microwave background.
Column 8: The distance to the group in millions of light years, usually
accurate to about 10% at best. An uncertain value is indicated
with a colon.
Column 9: Catalog names of the principal galaxies. NGC for those with no
prefix, otherwise from one of the following six catalogs:
IC, UGC, UGCA, ESO, MCG, PGC.

A diagram of all the galaxy groups listed above plotted onto the supergalactic plane. Our galaxy is in the middle, although the Local Group is not shown. Note the absence of any major galaxy groups above us on the map, this area is known as the Local Void, it is a sparse region of space with a diameter of over 100 million light years although it is not completely empty - there are some individual galaxies populating this region.
