AbstractThe following two facts are shown: 1.(i) There is a computable constant γ > 0 such that, given p0, there is a prime p > p0 satisfying p2|(km) for sufficiently large m, and 0≤k≤m with |m−2k| < m12 + γ (thus proving a conjecture of Erdős).2.(ii) For a positive integer a and a prime p, we have card{n<N: pa|(n2n)} ∼ N
