| Résumé : | One shows essentially that a geometry consisting of points and circles with any 3 distinct points on just one circle and such that any 4 non-concyclic points generate an inversive plane can only be the geometry induced on an ovoid of a projective space or an inversive plane; if the number of points is finite one can have only inversive planes. © 1971. |
