The dichromate and orientations of a graph
TL;DR: In this paper, the authors defined internal and external activities for any orientation of a graph relative to a fixed labeling of its edges and showed that the number of such orientations of having internal activity r and external activity s is 2r+sXrs where Xrs is the coefficient of xrys in the dichromate.

Finite projective geometries
TL;DR: In this paper, it was shown that there exist t - r collineations which together are transitive on the s-spaces of PG(t, p n) with the aid of primitive elements of Galois fields.
Families of Generalized Weighing Matrices
TL;DR: Generalized weighing matrices as mentioned in this paper are orthogonal matrices whose nonzero entries are roots of unity, and they are constructed with the aid of finite geometries which include as special cases interesting examples of conference matrices and weighted matrices.
