N-body simulations are here used to calculate the two-point correlation functions (TPCFs) of galaxy clusters in a set of cold dark matter/hot dark matter/baryon-containing hybrid models. The clusters of galaxies are identified so that their number density is the same as that of Abell clusters. Both the coherence length and the amplitude of the TPCFs systematically increase with the power of the initial density spectrum on large scales. These results suggest that the observed large correlation length of Abell clusters should be expected in models with enough power to explain galaxy clustering and large scale motions.
