A special case are the stabilizers of quadrangles in compact connected projective planes (i.e. automorphism groups of locally compact connected ternary fields).eninfo:eu-repo/semantics/openAccessAutomorphismengruppe , Stabile Ebene , Topologische Geometrie510Planar groups of automorphisms of stable planesarticle
