A Sylvester–Gallai configuration is a specific arrangement of points in a plane with some intriguing geometric properties. It consists of a finite set of points such that: 1. No three points are collinear. 2. There exists at least one line (the Sylvester–Gallai line) that passes through exactly two of the points in the configuration.
