摘要：

For any lambda > 1 we construct a periodic and locally finite packing of the plane with ellipses whose lambda-enlargement covers the whole plane. This answers a question of Imre Barany. On the other hand, we show that if C is a packing in the plane with circular disks of radius at most 1, then its (1 + 10(-5))-enlargement covers no square with side length 4.
