Let 𝒦 = {K1,K2,⋯} be an
infinite countable class of compact convex subsets of euclidean n-dimensional space
Rn. We shall say that 𝒦 permits a space covering or, more precisely, a covering of
Rn, if there are rigid motions σ1,σ2,⋯ such that Rn⊂⋃i=1∞σiKi. In this paper we
concern ourselves with necessary and sufficient conditions in order that a given class
𝒦 permits a space covering.
