We simulate sytems up to 10 001 x 10 001 x 10 001 in three dimensions
at the percolation threshold p(c) of 0.31160. We find that the fractal
dimension is similar or equal to 2.53 +/- 0.02, the cluster size dist
ribution exponent, tau, is 2.186 +/- 0.002 and an exponent of 0.85 des
cribing how the mass of the clusters scale with rank. Corrections-to-s
caling exponents of similar or equal to -0.7 are observed for n(s) and
for the mass of the largest cluster. We also check the percolation th
reshold and report good agreement with recent values.
