Abstract
The paper is an addition to the paper of Yu. I. Babenko and V. A. Zalgaller published in the same volume. It gives a condition under which the set of all vertices of several coaxial prisms inscribed in a sphere in \(\mathbb{R}_3\) has power invariants I1,...,In. A finite set in \(\mathbb{R}_3\) with 11 invariants is constructed. It is also proved that unions of prisms yield finite sets in \(\mathbb{R}_3\) with any preassigned number n of invariants with alternating signs. Bibliography: 5 titles.
