Query: Deformation Classification of Typical Configurations of 7 Points in the
  Real Projective Plane   A configuration of 7 points in RP2 is called typical if it has no collinear
triples and no coconic sextuples of points. We show that there exist 14
deformation classes of such configurations. This yields classification of real
Aronhold sets.
