With the availability of large-scale redshift survey data, it is now becomingpossible to explore correlations between large-scale structure and theproperties and morphologies of galaxy clusters. We investigate the spatialdistributions of a 98% complete, volume-limited sample of nearby (z<0.1) Abellclusters with well-determined redshifts and find that cooling flow clusterswith high mass-accretion rates have nearest neighbors which are much closerthan those of other clusters in the sample (at the 99.8% confidence level), andreside in more crowded environments out to 30/h Mpc. Several possibleexplanations of this effect are discussed.Comment: Astrophysical Journal Letters, in pres
