Abstract We announce the end of the classification of all firm and residually connected geometries satisfying the conditions (IP)_2 and (2T)_1 and on which the Mathieu group M_23 acts flag-transitively and residually weakly primitively. The complete list of geometries is available as a supplement to this paper.
