James Singer [12] has shown that there exists a collineation which is transitive on the (t - 1)-spaces, that is, (t - 1)-dimensional linear subspaces, of PG(t, pn). In this paper we shall generalize this result showing that there exist t - r collineations which together are transitive on the s-spaces of PG(t, pn). An explicit construction will be given for such a set of collineations with the aid of primitive elements of Galois fields. This leads to a calculus for the linear subspaces of finite projective geometries.

Finite projective geometries, especially the Fano plane, have been observed to arise in the context of certain quantum gate operators. We use Clifford algebras to explain why these geometries, both planar and higher dimensional, appear in the context of multi-qubit composite systems.

And Algebra

In recent years the subject of miniature or finite geometries has aroused some interest. Most studies to date have been concerned with the study of finite projective and affine (Euclidean) geometries, Many teachers have found this material simple enough to present to students studying geometry and algebra in high school. This paper proposes to describe axiomatically a large class of finite systems called finite Bolyai-Lobachevsky geometries. The approach will be geometric instead of algebraic, although to pursue the subject in depth algebraic techniques are needed. The Bolyai-Lobachevsky geometries can be presented in somewhat the same manner as the studies of finite projective geometries.
