Original conjecture (Lean type)
True ↔ ∃ k ≥ 2, ∃ n, ∃ m ≥ n + k, 25 = ↑(∏ i ∈ Finset.Icc 1 k, (m + i)) / ↑(∏ i ∈ Finset.Icc 1 k, (n + i))Original conjecture source: FormalConjectures/ErdosProblems/686.lean

Something wrong with this formalization?
A statement that does not faithfully capture the original conjecture is the one real risk here, so we would rather hear about it early - before someone spends weeks on it.
