Finite Fields - dvberkel/debruijn GitHub Wiki
Finite Fields are a mathematical abstractions which mimic well known structures such as the real numbers.
One way of representing final fields is via polynomial rings. For example a finite field of 9 elements can be represented by Z_3[x] modulo the polynomial x^2 + 1.
Application
For an application of the Finite Fields for the generation see "Fractals, Graphs and Fields" on the bibliography.
