Résumé : We define some linear spaces on the set of all proper subspaces of a triple system S(γ2,3,v). The connected components of these linear spaces are projective spaces of order 2 and punctured projective spaces of order 3, i.e. projective spaces of order 3 from which a point has been deleted. We show how these connected components can be used to find affine and projective factors in S(γ2,3,v). © 1987.
