boundopen_question
Erdős Problem #1148 has status 'proved (lean)'. Statement: Can every large integer $n$ be written as $n=x^2+y^2-z^2$ with $\max(x^2,y^2,z^2)\leq n$? This was proved affirmatively by Chojecki [Ch26], using a Duke-type equidistribution theorem. A Lean formalisation of the reduction (conditional on a Duke-type equidistribution theorem) exists; see the [forum discussion](https://www.erdosproblems.com/forum/thread/1148#post-4849). Topics: number theory. Erdős prize: no. Statement is machine-verified in Lean (formal-conjectures). OEIS: A390380, A393168.
