Primitive Root Modulo n - Order of Magnitude of Primitive Roots

Order of Magnitude of Primitive Roots

The least primitive root modulo p is generally small.

Let gp be the smallest primitive root modulo p in the range 1, 2, ..., p–1.

Fridlander (1949) and Salié (1950) proved that there is a positive constant C such that for infinitely many primes gp > C log p.

It can be proved in an elementary manner that for any positive integer M there are infinitely many primes such that M < gp < p – M.

Burgess (1962) proved that for every ε > 0 there is a C such that

Grosswald (1981) proved that if, then .

Shoup (1990, 1992) proved, assuming the generalized Riemann hypothesis, that gp =O(log6 p).

    “Remember, a woman has to work harder than a man and have more patience in order to achieve success.”
    —Margaret Mary Morgan, U.S. suffragist, print shop owner, and politician. As quoted in Dianne Feinstein, ch. 5, by Jerry Roberts (1994)

    “Although a man may lose a sense of his own importance when he is a mere unit among a busy throng, all utterly regardless of him, it by no means follows that he can dispossess himself, with equal facility, of a very strong sense of the importance and magnitude of his cares.”
    —Charles Dickens (1812–1870)

    “Deep down, the US, with its space, its technological refinement, its bluff good conscience, even in those spaces which it opens up for simulation, is the only remaining primitive society.”
    —Jean Baudrillard (b. 1929)

    “Now fades the lasts long streak of snow,
    Now burgeons every maze of quick
    About the flowering squares, and thick
    By ashen roots the violets blow.”
    —Alfred Tennyson (1809–1892)
