On non-normal partitions of Lobachevskij space. (Russian) Zbl 0739.51016
A partition \(P\) of the \(n\)-space \(S_ n\) into polytopes is regular if to any two polytopes there is a mapping of \(P\) carrying one polytope into any other. \(P\) is non-normal if in \(P\) there are couples of polytopes having \((n-1)\)-dimensional proper parts of the \((n-1)\)-faces in common.
Examples of infinite series of non-normal regular partitions of the 3-, 4- and 5-dimensional Lobachevskij space are presented.
