Generalized doubling for incidence geometries
2006An (incidence) geometry is a structure (X, , I, t) in which (X, ) is a simple graph and t is a surjective map from X onto a set I such that the pre-images t?1(i) are cocliques for each i 2 I. The rank of the geometry is the cardinality of the set I. The vertices of the graph underlying a geometry are called elements of the geometry.
