class Fractional k => FiniteField k where Source #

Type class for finite fields

Methods

order :: k -> Integer Source #

The order is number of elements of a finite field k. It of the form p^n, where p is prime number called the characteristic of the field, and n is a positive integer.

char :: k -> Integer Source #

The characteristic of a field, p.

pthRoot :: k -> k Source #

The inverse of Frobenius endomorphism x ↦ x^p.

allValues :: [k] Source #

All values of a field
