| چکیده | ||
| This paper introduces some new rank six geometries associated with the Fischer sporadic simple group Fi22. These geometries are both residually connected and firm, with Fi22 acts as a flag-transitive automorphism group on them. The previously known geometries for Fischer sporadic simple group Fi22 have rank at most four. Therefore, we investigate improvements to the lower bound of the maximum rank of the residually connected and firm geometries on which the group Fi22 acts as a flag-transitive automorphism group. Moreover, we demonstrate that the independent generating set of Fischer sporadic simple group Fi22 has a size of at least seven. | ||
