We consider percolation in d dimensions for finite samples of linear s
ize L. Theoretical arguments are presented to show that for d > 6, the
shift in the percolation threshold, p(c)(L) - p(c)(infinity, behaves
like A/L(2) + B/L(d/3); for periodic boundary conditions, A = 0. These
predictions are consistent with recent simulations in seven dimension
s.
