Notes. The top and bottom halves respectively include the phase 2 and 3 groups. The last two columns respectively list the H I masses inside and outside the discs of the member galaxies.
( * )LEDA 749936 (WISEA J220854.95-274701.6) coincides spatially with the peak of an H I cloud in the core of HCG 91, but lacks an optical readshift; we include it in this table but do not count it as a core member.
