Statement
Setting (pp. 2--3, 6--7). is an irrational vector: are linearly independent over the rationals. A bounded measurable is a bounded remainder set (BRS) if some constant satisfies for and almost every , where (display (2.1), p. 6); it is Riemann measurable if its boundary has measure zero (p. 7).
Theorem 4 (p. 5, quoted). "For a convex polytope in to be a bounded remainder set, it is necessary that is centrally symmetric and has centrally symmetric -dimensional faces."
Corollary 4 (p. 5). A convex polyhedron in with vertices in is a BRS if and only if it is a zonohedron, that is, centrally symmetric with centrally symmetric faces. The paper obtains it (p. 30) from Theorem 4 and Corollary 1 (p. 2, recorded on the Theorem 1 page), since in dimension three the two classes of polytopes coincide; it notes that for the class in Theorem 4 is strictly larger than the zonotopes.
Read depth. Claims checked: Theorem 4, Corollary 4 and the proof on p. 30 were read clause by clause on the page images; the cited result of Mürner and Theorem 5.1 were not checked. Nothing here is independently reviewed.

Proof pointer
P. 30. By Theorem 5.1 (p. 27) a bounded remainder polytope has vanishing Hadwiger-type invariants for the group ; these force the classical Hadwiger invariants (for all translations) to vanish, and a result of Mürner, which the paper cites, says that for a convex polytope this is equivalent to central symmetry of the polytope and of its -dimensional faces.
