Résumé : The residually weakly primitive geometries of M22 are studied. The classification of all firm and residually connected geometries satisfying the conditions (IP)2 and (2T)1 is performed. It is found that the Mathieu group M22 acts flag-transitively and residually weakly primitively on these geometries.
