Query: Precise determination of the conductivity exponent of 3d percolation
  using "Percola"   Using 20 months of CPU time on our special purpose computer ``Percola'' we
determined the exponent for the normal conductivity at the threshold of
three-dimensional site and bond percolation. The extrapolation analysis taking
into account the first correction to scaling gives a value of $t/\nu = 2.26\pm
0.04$ and a correction exponent $\omega$ around 1.4.
