In this paper, we present multi parametric quadgraph equations which are consistent around the cube. These equations are obtained by applying a ‘double twist ’ to known integrable equations. Furthermore, we perform a limit to one of these equations to derive the non-symmetric equation which is Equation 19 in [7]. As a result, we obtain a novel Lax pair of this equation. 1
