  We show that Compact Groups of Galaxies (CGs) are frequently associated with
larger-scale structures, and such associations become more frequent for CGs
selected by the same criteria at higher redshifts. Our findings suggest that
CGs are an intrinsic part of the cosmological structure formation process and
are consistent with the LambdaCDM (or "concordance") model, but only if galaxy
formation is a biased process.
