Abstract
We show that the geometric algebraCℓ 3 can be used as a model for the real projective plane, in the sense that the axioms defining the plane and their duals can be proved as theorems. However, it seems that there is some difficulty in using a geometric algebra to model a projective space over a noncommutative division ring.
