Erdős Problem #350 has status 'proved (lean)'. Statement: If `A ⊂ ℕ` is a finite set of integers all of whose subset sums are distinct then `∑ n ∈ A, 1/n < 2`. Proved by Ryavec. This was proved by Ryavec, who did not appear to ever publish the proof. Ryavec's proof is reproduced in [BeEr74]. More generally, Ryavec's proof delivers that $\sum_{n\in A}\frac{1}{n}\leq 2-2^{1-\lvert A\rvert},$ with equality if and only if $A=\{1,2,\ldots,2^k\}$. This was formalized in Lean by Alexeev using Aristotle. Topics: number theory, additive combinatorics. Erdős prize: no. Statement is machine-verified in Lean (formal-conjectures). OEIS: N/A.
