DESCRIPTION:Considering the crystal limit of the modular XXZ spin-chain I 
 will show that one arrives at a purely combinatorial construction of the f
 usion ring (also known as Verlinde algebra) of  su(n) Wess-Zumino-Novikov-
 Witten (WZNW) conformal field theory. The transfer matrix and Baxter's Q-o
 perator have a well defined meaning in this limit: they correspond to symm
 etric polynomials in non-commutative variables which are related to Kashiw
 ara's crystal operators.\n
