Résumé : We prove the existence of a rank three geometry admitting the Hall-Janko group J2 as flag-transitive automorphism group and Aut(J2) as full automorphism group. This geometry belongs to the diagram (c · L*) and its nontrivial residues are complete graphs of size 10 and dual Hermitian unitals of order 3.
