In Research problem 41, \textit{J. M. Wills} formulates the 'space conjecture' concerning inequalities for the maximal packing density and minimal covering density of k balls respectively. In Research problem 42, \textit{L. Fejes Tóth} rephrases and generalizes the Robinson problem in asking for values of M(r), the maximum of the average number of neighbours extended over all packings circles of radius r.
