The central problem for Jackson sets is the following: is every finite set with two or more points Jackson. This problem has been raised by Jackson in the context of the solution of a problem of Steinhaus [see e.g. {\it S. Jackson} and {\it R. D. Mauldin}, Bull. Symb. Log. 9, 335‒361 (2003; Zbl 1070.52008)]. Jackson proved that every set of three points in $\mathbb R^{2}$ is Jackson. In the present article the authors give several contributions to this problem including the following interesting result: The set of vertices of the unit square is Jackson. The article closes with several open questions. rv: Peter M. Gruber (Wien)
