We give a detailed description of a dynamical system which enjoys a Poisson–Lie symmetry with two non-isomorphic dual groups. The system is obtained by taking the $q\to\infty$ limit of the $q$-deformed WZW model and the understanding of its symmetry structure results in uncovering an interesting duality of its exchange relations.
Keywords: Poisson–Lie symmetry; WZW model.
