He says "Although both authors state their bounds only for primitive roots, the bounds actually hold for prime primitive roots as well." Can you explain why? $\endgroup$ – GH from MO Nov 16 '12 at   1. Wilson's Theorem: Wilson's theorem states that a natural number n > 1 is a prime number if and only if. 2. Fermat's Little Theorem: Fermat's little theorem states that if p is a prime number, then for any integer a, the number a p − a is an.

Notes on primitive roots We showed in class that if pis prime, then there exist primitive roots mod p. For odd primes p, we will now show that there exist primitive roots modulo pk and 2pk for all k≥ 1. Theorem 1. Let pbe an odd prime. (a) If gis a primitive root mod p, then either gor g+pis a primitive .

is a complete set of incongruent primitive roots of Exercise 4. (a) Let r be a primitive root of a prime p. If p ≡ 1 mod 4, show −r is also a primitive root. (b) Find the least positive residue of the product of a set of φ(p −1) incongruent primitive roots modulo a prime p. (c) Let p be a prime of the form p = 2q +1 where q is an odd.   Proposition Ifp and q = 8p+ 1 are both odd primes with p > 11, then 3 is a primitive root o] q. Proposition If p and q = 16p + 1 are both odd primes with p > , then 3 is a primitive root of q. Proposition If p and q p + 1 are both odd primes with p > , then 3 is a primitive root of q.

REVIEWS AND DESCRIPTIONS OF TABLES AND BOOKS 18 [F].—Roger Osborn, Tables of All Primitive Roots of Odd Primes Less thanUniversity of Texas Press, Austin,70 p., 30 cm. Price$ This slim volume lists primitive roots of the odd primes less than These tables were computed on an IBM Although primitive roots have played an important role in the development of the classical theory of numbers, knowledge of their distribution is still limited.

The Naval Research Laboratory has produced and publishes herein a table of all the primitive roots of the primes less thanthe most extensive tabulation of its kind now available. primitive roots of pk, where k ≥ 2, and p is an odd prime.1 The construction builds on the above result of Niven et al.

, and allows us to construct the primitive roots of arbitrary prime powers in terms of the primitive roots of the primes.

2 Preliminaries Let n be a positive integer, and. A prime number (or prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. By Euclid's theorem, there are an infinite number of prime s of the prime numbers may be generated with various formulas for first primes are listed below, followed by lists of notable types of prime numbers in alphabetical order, giving their.

We need to find all primitive roots of the primes. For p = From the table given on pagein the book the least primitive root for 11 is 2. We find all primitive roots of the form.

We know by theorem that if a has order k modulo n then has the order. Since 2 is primitive root of 11, order of 2 is. Now, has order 10 if and only if.

Primitive roots do not necessarily exist mod n n n for any n n n. Here is a complete classification: There are primitive roots mod n n n if and only if n = 1, 2, 4, p k, n = 1,2,4,p^k, n = 1, 2, 4, p k, or 2 p k, 2p^k, 2 p k, where p p p is an odd prime.

So I encountered this proof on a Number Theory book, I will link the pdf at the end of the post (proof at page 96), it says: "Every prime has a primitive root, proof: Let p be a prime and let m be a positive integer such that: p−1=mk for some integer F(m) be the number of positive integers of order m modulo p that are less than p.

The complete answer is stated in the so-called primitive root theorem, whose proof is the main reason for this lecture. Theorem 9 (The Primitive Root Theorem).

Let n equal 2 or an odd prime power. Then there exist primitive roots modulo n and also modulo 2n. There are no primitive roots with any other moduli.

To prove the primitive root theorem. We will prove the existence of primitive roots, first modulo primes and later modulo odd prime powers (also the cases $2p^{\alpha}$ will be dealt with, and modulo $2^{\alpha}$ we ''almost'' have a primitive root).

As usual, if one controls prime moduli, it is not very hard to control prime power moduli. 4- If it is 1 then 'i' is not a primitive root of n. 5- If it is never 1 then return i.

Although there can be multiple primitive root for a prime number but we are only concerned for smallest you want to find all roots then continue the process till p-1 instead of breaking up on finding first primitive root.

primitive roots modulo p, but how do we ﬁnd one. This is a much deeper ques-tion. Suppose for instance we ask whether 2 is a primitive root modulo p.

Well, it depends on p. Among odd primes less than2 is a primitive root modulo 3, 5, 11, 13, 19, 29, 37, 53, 59, 61, 67, 83 and is not a primitive. a primitive root mod p.

2 is a primitive root mod 5, and also mod 3 is a primitive root mod 7. 5 is a primitive root mod It can be proven that there exists a primitive root mod p for every prime p. (However, the proof isn’t easy; we shall omit it here.) 3) For each primitive root b in the table, b 0, b 1, b 2,b p − 2 are all.

Section - Perfect Numbers and Mersenne Primes 1. From Class: Show that every Mersenne prime greater than three ends in either a 1 or a 7. Solution: Note that if M is a Mersenne prime other than three, then M = 2p − 1 where p is an odd integer.

We claim that 2odd always ends in a 2 or an 8. It should be clear how the result about Mersenne. Therefore, every prime number other than 2 is an odd number, and is called an odd prime. Similarly, when written in the usual decimal system, all prime numbers larger than 5 end in 1, 3, 7, or 9.

The numbers that end with other digits are all composite: decimal numbers that end in 0, 2, 4, 6, or 8 are even, and decimal numbers that end in 0 or 5 are divisible by 5. We will find the primitive roots of First, recall an important theorem about primitive roots of odd primes: Let F denote the Euler phi function; if p is an odd prime, then p has F(F(p)) = F(p-1) primitive roots.

Since F(F(11)) = F(10) = 4, we know that 11 has four primitive roots. Given a task is to count all the primitive roots of. A primitive root is an integer x (1 primitive root modulo 3 is 2. Input: P = 5 Output: 2 Primitive roots modulo 5 are 2 and 3. Primitive roots De nition A generator of (Z=p) is called a primitive root mod p.

Example: Take p= 7. Then 23 1 mod 7; so 2 has order 3 mod 7, and is not a primitive root. However, 32 2 mod 7;33 6 1 mod 7: Since the order of an element divides the order of the group, which is 6 in. primitive root mod p by a theorem we proved in class. 5. Let p be an odd prime, and suppose 1 primitive root modulo p if and only if for all primes q dividing p−1, a(p−1)/q 6≡1 mod p.

Hint: One direction is very easy. For the other direction, if a is not a primitive root, then.The following facts about primitive roots of an odd prime seem to be well known.

For example, they both appear as exercises in Burton's Elementary Number Theory. Primitive roots of odd primes. Ask Question Asked 8 years, 6 months ago. Active 8 years, Primitive roots for primes (Burton's text book.for least primitive roots, least prime primitive roots, least prime base required to prove the primality of a number, as well as empirical estimates of the Artin constant and of the average value of the least (prime) primitive root.
