The values critical temperature of infinite lattice (Tc=6.680(1), Tc=6.680(3), Tc=6.691(28), Tc=6.723(15), Tc=6.793(52), Tc=6.938(85), Tc=6.997(62), Tc=7.284(45), Tc=7.797(51), Tc=8.539(3)) are obtained from the straight line fit of the magnetic susceptibility maxima for h=0, h=0.00025, h=0.00050, h=0.001, h=0.0025, h=0.0050, h=0.01, h=0.025, h=0.050, h=0.1, respectively. Although the values obtained of correction infinite lattice critical temperature (Tc=6.680(1), Tc=6.680(3)) are in agreement with series expansion (Tc=6.6802, Tc=6.682) (94,95), Monte Carlo (Tc=6.680, Tc=6.6803) (73-95) and Creutz Cellular Automaton (Tc=6.6800, Tc=6.6700) (44-49) for h=0, h=0.00025, the values obtained of correction infinite lattice critical temperature (Tc=6.691(28), Tc=6.723(15), Tc=6.793(52), Tc=6.938(85), Tc=6.997(62), Tc=7.284(45), Tc=7.797(51), Tc=8.539(3)) aren?t in agreement with series expansion Tc=6.6802, Tc=6.682) (94,95), Monte Carlo (Tc=6.680, Tc=6.6803) (73-95) and Creutz Cellular Automaton (Tc=6.6800, Tc=6.6700) (44-49) for h=0.00050, h=0.001, h=0.0025, h=0.0050, h=0.01, h=0.025, h=0.050, h=0.1.
