Résumé : A π-space is a planar space all of whose planes are isomorphic to a given linear space π. Examples are given by projective and affine spaces. The smallest linear space π having lines of different sizes for which the existence of a π-space is still unsolved has 7 points and the corresponding π-space would be a regular space of 47 points. We prove that such a π-space is rigid, i.e. has no other automorphism than the identity. © 1983.
