  We exploit the local loop dynamics calculated in prepotential formulation to
compute the pertrubation expansion in the strong coupling limit of lattice
gauge theory. A new exact simulation technique is developed to simulate all
possible loop states on an infinite lattice using exact BFACF algorithm. This
loop perturbation numerical calculations are free from any limitation on
lattice size. Using this, we calculate the correction of string tension for
SU(2) theory in 2+1 dimension upto order $g^{64}$.
