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).

Famous quotes containing the words order of, order, magnitude, primitive and/or roots:
“An example is often a deceptive mirror, and the order of destiny, so troubling to our thoughts, is not always found written in things past.”
—Pierre Corneille (1606–1684)
“To compose our character is our duty, not to compose books, and to win, not battles and provinces, but order and tranquillity in our conduct.”
—Michel de Montaigne (1533–1592)
“We quaff the cup of life with eager haste without draining it, instead of which it only overflows the brim—objects press around us, filling the mind with their magnitude and with the throng of desires that wait upon them, so that we have no room for the thoughts of death.”
—William Hazlitt (1778–1830)
“Perhaps our own woods and fields,—in the best wooded towns, where we need not quarrel about the huckleberries,—with the primitive swamps scattered here and there in their midst, but not prevailing over them, are the perfection of parks and groves, gardens, arbors, paths, vistas, and landscapes. They are the natural consequence of what art and refinement we as a people have.... Or, I would rather say, such were our groves twenty years ago.”
—Henry David Thoreau (1817–1862)
“A poet must be a psychologist, but a secret one: he should know and feel the roots of phenomena but present only the phenomena themselves—in full bloom or as they fade away.”
—Ivan Sergeevich Turgenev (1818–1883)
