Bound findings

Erdős Problem #120 remains OPEN. Statement: Let $A \subseteq \mathbb{R}$ be an infinite set. Must there be a set $E \subseteq \mathbb{R}$ of positive measure which does not contain any set of the shape $a * A + b$ for some $a,b \in \mathbb{R}$ and $a \neq 0$? Topics: combinatorics. Erdős prize: $100. Statement is machine-verified in Lean (formal-conjectures). OEIS: N/A.
