Abstract
In this study, the geometric representation of an Orthogonal Array is
obtained using finite analytic projective geometry of the Galois field GF(s)
of t-dimensions, which can be denoted by PG(t; s), where s is a prime or
a power of a prime number. We give relations between the parameters of
Orthogonal Arrays and properties of the projective geometry and of related
geometries. We offer some geometrical examples.
