Title:  On packing squares with equal squares. (In English)
Source:  J. Comb. Theory, Ser. A 19, 119-123 (1975).
Review:  Let \alpha be a positive real number. Let N(\alpha) denote the maximum number of nonoverlapping open unit squares that can be packed into a square of side \alpha. By a clever construction it is shown that \alpha 2-N(\alpha) = 0(\alpha 7/11). The authors raise a number of related questions.
