    "abstract": "We describe a scheme of constructing classical integrable models in\n2+1-dimensional discrete space-time, based on the functional tetrahedron\nequation - equation that makes manifest the symmetries of a model in local\nform. We construct a very general \"block-matrix model\" together with its\nalgebro-geometric solutions, study its various particular cases, and also\npresent a remarkably simple scheme of quantization for one of those cases.",
