Erdős problem 445Is it true that, for any c>1/2c>1/2, if pp is a sufficiently large prime then, for any n≥0n\geq 0, there exist a,b∈(n,n+pc)a,b\in(n,n+p^c) such that ab≡1(modp)ab\equiv 1\pmod{p}?WorkspaceContinue locallyOpen sourceSign in to contributeOpen this exact Problem, source revision, and authority Repository in Workbench.
