theorem erdos_421 :
(∃ (d : ), StrictMono d 1 d 0 (Set.range d).HasDensity 1 Set.InjOn (fun (x : × ) => match x with | (u, v) => iFinset.Icc u v, d i) {(u, v) : × | u v}) sorry

Is there a sequence $1 \le d_1 < d_2 < \dots$ with density 1 such that all products $\prod_{u \le i \le v} d_i$ are distinct?
