The supercluster has 16 members, all with measured redshifts, and is one of the richest [[Supercluster|superclusters]] in the region. The members include [[Abell 1289]], [[Abell 1302]], [[Abell 1322]], [[Abell 1366]], [[Abell 1402]], [[Abell 1406]], [[Abell 1421]], [[Abell 1432]], [[Abell 1446]], [[Abell 1477]], [[Abell 1518]], [[Abell 1559]], [[Abell 1566]], [[Abell 1621]], [[Abell 1646]], and [[Abell 1674]].
