  A "friends-of-friends" percolation algorithm has been used to extract a
catalogue of drho/rho = 80 density enhancements (groups) from the six slices of
the Las Campanas Redshift Survey (LCRS). The full catalogue contains 1495
groups and includes 35% of the LCRS galaxy sample. A statistical sample of 394
groups has been derived by culling groups from the full sample which either are
too close to a slice edge, have a crossing time greater than a Hubble time,
have a corrected velocity dispersion of zero or less, or contain a 55 arcsec
"orphan" (a galaxy with a "faked" redshift excluded from the original LCRS
redshift catalogue due to its proximity --- i.e., within 55 arcsec --- of
another galaxy). Median properties derived from the statistical sample include:
line-of-sight velocity dispersion sigma_los = 164 km/s, crossing time t_cr =
0.10/H_0, harmonic radius R_h = 0.58/h Mpc, pairwise separation R_p = 0.64/h
Mpc, virial mass M_vir = (1.90x10^13)/h M_sun, total group R-band luminosity
L_tot = (1.40x10^11)/h^2 L_sun, and R-band mass-to-light ratio M/L = 153h
M_sun/L_sun.
