Step-by-step explanation:
The first few for which primitive roots exist are 2, 3, 4, 5, 6, 7, 9, 10, 11, 13, 14, 17, 18, 19, 22, ... (OEIS A033948), so the number of primitive root of order for , 2, ... are 0, 1, 1, 1, 2, 1, 2, 0, 2, 2, 4, 0, 4, ... (OEIS A046144).
A primitive polynomial is a polynomial that generates all elements of an extension field from a base field. Primitive polynomials are also irreducible polynomials. For any prime or prime power and any positive integer , there exists a primitive polynomial of degree over GF( ).
