**
A few open problems related to modular properties of
determinants of symmetric matrices defined by binomial coefficients
**

**
A short description of the main result of my preprint "Counting Triangulations of Configurations"
**

** An applet written by my collegue Jean-Marc Decauwert which allows
you to experiment with the Orchard relation (an equivalence relation
on a finite set of points in R^2 which does not contain three aligned points).
**

(genericity), described in "Le cocycle du verger", CRAS 338 (2004), 187-190
and in "The Orchard relation of planar configurations of points I,II
(coauthor D. Garber) to appear in Geombinatorics (I believe).
You can create a point by a mouse-click (cr'eer),
move a point (click on a point and drag it with clicked mouse) (d'eplacer)
or remove a point (supprimer).
Enabling the option "afficher" displays all lines determined by
pairs of distinct points.
