The Hesse configuration is a specific geometric arrangement in projective geometry, particularly concerning the configuration of points and lines in a projective plane. It consists of a set of points and lines where certain incidence properties hold. In the case of the classical Hesse configuration: - It includes 9 points and 9 lines. - Each point lies on exactly 3 lines, and each line contains exactly 3 points.
