Abstract
Recently, Mukherjee, Choudhury, and Chowdhury presented a new discrete integrable system. Based on its Lax pairs, we construct infinitely many conservation laws and Darboux transformation for the discrete system. As an application of the Darboux transformation, we carry out a new exact solution of the discrete system.
