The density of N-clusters(the clusters which contain N galaxies)in the Universe is shown from observations to scale with N as nN ∝ N^-τ with τ=3/γ+1 and the correlation exponent γ≈1.8.Correspondingly,a acaling relation τ=29-9γ/12-4γ between the two exponents,which agrees with the observations,is found analytically in our naive clustering model.
