A Π-zonotope is a zonotope that can be obtained from permutahedron by deleting zone vectors. Any face F of codimension 2 of such zonotope generates its belt, i.e. the set of all facets parallel to F. The belt diameter of a given zonotope Z is the diameter of the graph with vertices correspondent to pairs of opposite facets and with edges connect facets in one belt.In this paper we investigate belt diameters of Π-zonotopes. We prove that any d-dimensional Π-zonotope (d≥3) has belt diameter at most 3. Moreover if d is not greater than 6 then its belt diameter is bounded from above by 2. Also we show that these bounds are sharp. As a consequence we show that diameter of the edge graph of dual polytope for such zonotopes is not greater than 4 and 3 respectively.
