Abstract
We prove that a disjoint family of six or more unit circular disks in the plane has a common support line provided every its subfamily of three disks has a common support line. This result is in contrast with the known fact that the existence of a transversal line to a finite family of unit disks is not guaranteed by the transverality of every its subfamily of three disks. A new method of proof, which combines continuity arguments and usage of geometric computer software, is elaborated.
