On the basis of loop group decompositions (Birkhoff decompositions), we give a discrete version of the nonlinear d’Alembert formula, a method of separation of variables of difference equations, for discrete constant negative Gauss curvature (pseudospherical) surfaces in Euclidean three space. We also compute two examples by this formula in detail.
