RésumeIt is known that associated with square of certain Coxeter element there exists the cluster algebra of finite type, which has only finitely many cluster variables. For type A case, we shall present its all cluster variables and describe them in terms of monomial realizations of Demazure crystals. (This is a joint work with \href{http://rscdb.cc.sophia.ac.jp/Profiles/16/0001568/prof_e.html}{Y. Kanakubo}.)
