Abstract
Steinhaus' lattice points problem addresses the question of whether it is possible to cover exactly $n$ lattice points on the plane with an open ball for every fixed nonnegative integer $n$. This paper includes a theorem which can be used to solve the general problem of covering elements of so-called quasi-finite sets in Hilbert spaces. Some applications of this theorem are considered.
