Directional percolation of dimer on simple cubic lattice

We consider the model dimer (extended objects of the size 2) of site directional percolation on simple cubic lattice. The percolation threshold is estimated as $p_c=0.27961\pm0.00004$ for unidirectional percolation problem, and $p_c=0.26192\pm0.00004$ for bidirectional percolation problem. The jamming threshold is estimated as $p_\mathrm{jam}=0.827\pm0.002$ for unidirectional percolation problem, and $p_\mathrm{jam}=0.839\pm0.001$ for bidirectional percolation problem.
