Monte Carlo simulations alone could not clarify the corrections to scaling
for the size-dependent p(c)(L) above the upper critical dimension. Includin
g the previous series estimate for the bulk threshold p(c)(infinity) gives
preference for the complicated corrections predicted by renormalisation gro
up and against the simple 1/L extrapolation. Additional Monte-Carlo simulat
ions using the Leath method corroborate the series result for p(c).
