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_22 acts flag-transitively and residually weakly primitively. The complete list of geometries is available as a supplement to this paper. Download a PostScript or a DVI version of the supplement. Download the geometries of M_22 as a gzipped tarred magma file.
