Abstract.
A set C in the Euclidean space \({\mathbb{R}}^d\) is called isometrically m-divisible if there exists a disjoint decomposition of C into m subsets C i pairwise congruent with respect to the group of Euclidean isometries. We present a necessary condition for the isometric m-divisibility, which shows in particular that most convex bodies – in the sense of Baire category – are not isometrically m-divisible for any choice of m \(m \in \{2, 3, \ldots, \aleph_0 \}\).
