Complete Classification of Flag-Transitive Point一Primitive
- G/ x& j( E; B) W/ P2 r                  2-Designs with Socle

        In recent years several authors have determined some 2-designs with flag-transitive point-primitive automorphism group G of almost simple type with sporadic socle. Here we obtain the complete classification of flag-transitive point-primitive non-trivial 2-designs with socle Mli，and find that there are precisely 14 such nonisomorphic 2-designs.
