| Abstract:
An n3 configuration
consists of a set of n points
and n lines such that each line is incident on
3 points, and each point is incident on 3 lines.
The book Geometry and the Imagination by
Hilbert and Cohn-Vossen contains much material
on n3 configurations. In recent years they
have been studied by Grunbaum, Sturmfels,
Bokowski, Pisanski, Gropp, and others, using
algebraic, geometric, and combinatorial methods.
The Georges configuration is a 253 configuration,
introduced by Grunbaum. He recently proved
that it has a coordinatization in the real plane.
I have recently found a rational coordinatization
of it, by finding roots of a coordinatizing polynomial.
This method of constructing a coordinatizing
polynomial and its application to the Georges
configuration will be presented.
