We consider a modification of the classical number theoretic question about the gaps between consecutive primitive roots modulo a prime p, which by the well-known result of Burgess are known to be at most p1/4+o(1). Here we measure the distance in the Hamming metric and show that if p is a sufficiently large r-bit prime, then, for any integer n∈[1, p], one can obtain a primitive root modulo p by changing at most 0.11002786… r binary digits of n. This is stronger than what can be deduced from the Burgess result. Experimentally, the number of necessary bit changes is very small. We also show that each Hilbert cube contained in the complement of the primitive roots modulo p has dimension at most O(p1/5+ϵ), improving on previous results of this kind.
