Reviewable change
back to reviewErdős Problem #694 has status 'solved (lean)'. Statement: Let $f_\max(n)$ be the largest $m$ such that $\phi(m) = n$, and $f_\min(n)$ be the smallest such $m$, where $\phi$ is Euler's totient function. Investigate $$ \max_{n\leq x}\frac{f_\max(n)}{f_\min(n)}. $$ GPT-5.5 Pro (prompted by Price) has proved (see also the comments for a summary) that $$ \max_{n\leq x}\frac{f_{\max}(n)}{f_{\min}(n)}=(e^\gamma+o(1))\log\log x. $$ A Lean formalisation of the reduction exists, conditional on Mertens' product theorem and Linnik's theorem; see the [formal proof](https://github.com/Shashi456/erdos-formalizations/blob/main/Erdos/P694/Proof.lean). Topics: number theory. Erdős prize: no. Statement is machine-verified in Lean (formal-conjectures). OEIS: possible.

vf_548d85ccc6d3d37cRead-only frontier; diff not recomputed.
Erdős problems frontier receives a reviewable source, finding, caveat, replication, evaluation, or proof-affecting edit.
The packet names affected record objects, evidence, rationale, reviewer-facing fields, and expected proof impact.
Schema, provenance, benchmark, contradiction, and proof checks decide whether the request is ready to read.
A steward accepts, rejects, caveats, revises, or retracts the request under an inspectable identity.
Only the accepted event mutates frontier state. Atlases, constellations, and search update from that record state.
