Every problem here was open when it entered the pool.
Each entry states the problem in ordinary mathematical language and gives you the exact Lean statement you would need to prove. Nothing is paraphrased, so what you read is what gets checked.

Erdős problem 930
Is it true that, for every r, there is a k such that
if I1,…,Ir
are disjoint intervals of consecutive integers,
all of length at least
True ↔
∀ r > 0,
∃ k,
∀ (I₁ I₂ : Fin r → ℕ),
(∀ (i : Fin r), 0 < I₁ i ∧ I₁ i + k ≤ I₂ i + 1) →
(∀ (i j : Fin r), i < j → I₂ i < I₁ j) → ¬Erdos930.IsPower (∏ i, ∏ m ∈ Finset.Icc (I₁ i) (I₂ i), m)

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.
