    "abstract": "We construct local M-operators for an integrable discrete time version of the\nclassical Heisenberg magnet by convolution of the twisted quantum trigonometric\n4$\\times$4 R-matrix with certain vectors in its \"quantum\" space. Components of\nthe vectors are identified with $\\tau$-functions of the model. Hirota\u0027s\nbilinear formalism is extensively used. The construction generalizes the known\nrepresentation of M-operators in continuous time models in terms of Lax\noperators and classical $r$-matrix.",
