[#R1495] Current status and exact unresolved remainder

claim. OPEN as checked on 2026-08-01. Strongest checked neighboring result: Current cited bounds give \(\sqrt2\le\liminf R(k)^{1/k}\le\limsup R(k)^{1/k}\le3.7992\ldots\). Exact unresolved remainder: Even existence of the limit is unknown, as is its value.

1Summary

The problem was checked as open on 2026-08-01.

The strongest neighboring result found in the cited sources is: Current cited bounds give \(\sqrt2\le\liminf R(k)^{1/k}\le\limsup R(k)^{1/k}\le3.7992\ldots\).

Supported evidence. Replay readiness: source only.

3Overview

The exact unresolved remainder is: Even existence of the limit is unknown, as is its value.

A complete resolution must meet the following acceptance conditions: - Prove convergence of \(R(k)^{1/k}\) and identify the limit, or prove that the sequence has no limit.
