Scaling behavior in very small percolation lattices

We examine the average cluster distribution as a function of lattice probability for a very small $\mathrm{}(L=6\mathrm{})\mathrm{}$ lattice and determine the scaling function of three-dimensional percolation. The behavior of the second moment, calculated from the average cluster distribution of $L=6\mathrm{}$ and $L=63\mathrm{}$ lattices, is compared to power-law behavior predicted by the scaling function. We also examine the finite-size scaling of the critical point and the size of the largest cluster at the critical point. This analysis leads to estimates of the critical exponent $\nu$ and the ratio of critical exponents $\beta /\nu$.
