Abstract
The cluster density function of independent percolationκ in ad-dimensional lattice is considered. For eachn, it is shown thatκ(p) has finitenth leftderivative at critical probabilityp c ifd is sufficiently large. This result agrees with the Bethe lattice approximation, where thenth one-sided derivative ofκ(p) is bounded atp c for alln.
