Descriptions: (Abstract of the paper)
We have acquired redshifts for a complete sample of 351 Abell clusters
with tenth-ranked galaxy magnitudes (m10) less than or equal to
16.5, including 115 entirely new cluster redshifts. The survey
includes all such clusters which lie north of δ=-27deg30arcmin
and is the largest magnitude-limited redshift survey of rich clusters
to date. Analysis of the spatial distribution of these clusters
reveals no clustering on scales larger than 75h-1Mpc; we do not
detect the large supercluster complexes reported by Tully. The
correlation length is 20.0(±4.3)h-1Mpc, consistent with the
results from other surveys. The frequency of voids with radii of order
60h-1Mpc or less is consistent with the form and amplitude of the
observed two-point correlation function. There is no significant
difference between the clustering properties of RC = O and RC ≥ 1
clusters. A percolation analysis yields 23 superclusters, 17 of which
are new. The superclusters are not significantly elongated in the
radial direction; large-scale peculiar motions are of order 1000 km
s-1 or less. Dramatically new constraints on the large-scale cluster
distribution will require surveys an order of magnitude larger.

Notes (1):
Note that due to the different origin of the data, m1 can be higher
than m10 (e.g. for A1892). Moreover, the magnitude scale for northern
clusters (A1-A2712) is different from that for the southern clusters
(A>2712). Trailing zeroes in m1, m10 and Zest were truncated at CDS.
