Systematising ideas by Poizat and Wagner, we avoid incidence geometries and use group actions instead; the proof becomes short and completely elementary.enExposition (narrative)Rank (graph theory)MathematicsGroup (periodic table)Calculus (dental)Elementary proofCombinatoricsDiscrete mathematicsPure mathematicsAlgebra over a fieldA self-contained guide to Frécon's theoremarticle
