Abstract
The Niemeyer-van Leeuwen formulation of the renormalisation group is used to describe a quenched dilute Ising model on a triangular lattice in two dimensions. The two- and three-cluster approximations are applied to calculate the probability dependence of the critical temperature Tc(p) and the critical exponents near the percolation threshold phi =1 is found to be in agreement with previous epsilon expansion results.
