Abstract:
    Redshift Survey Compact Groups (RSCGs) are tight knots of N>=3
    galaxies selected from the CfA2+SSRS2 redshift survey. The selection
    is based on physical extent and association in redshift space alone.
    We measured 300 new redshifts of fainter galaxies within 1h^-1^Mpc of
    14 RSCGs to explore the relationship between RSCGs and their
    environments. Thirteen of 14 RSCGs are embedded in overdense regions
    of redshift space. The systems range from a loose group of five
    members to an Abell cluster. The remaining group, RSCG 64, appears
    isolated. RSCGs are isolated and distinct from their surroundings to
    varying degrees, as are the Hickson compact groups. Among the 13
    embedded RSCGs, three are distinct from their general environments
    (RSCG 9, RSCG 11, and RSCG 85).

Note (1): Z = ZCAT (Cat. <VII/193>), F = new FAST spectrum
Note (2): "env. of 73" indicates that the galaxy is in the environment of
            RSCG 73, which we identified with the friends-of-friends
            algorithm
