Authored summary

Unresolved in this packet after the dated source check. Strongest checked result: The MathOverflow and Mathematics Stack Exchange versions have no answers. The source reports explicit reductions for heights 3 through 19 but no uniform construction, and the later exact-title search found no resolution. Exact unresolved remainder: Give a construction of a legal move sequence for every h>=3, with a proof that the recursive construction terminates at the root, or exhibit a height h and an invariant proving that no root-gathering sequence exists. For any individual-height computation, provide the complete move list and replay it with exact frog counts and graph distances; finite height checks alone do not settle the universal target.

The record cites sources for its explanation.

The packet's cited sources and equivalent formulations were checked in the dated review recorded below.

Strongest checked result: The MathOverflow and Mathematics Stack Exchange versions have no answers. The source reports explicit reductions for heights 3 through 19 but no uniform construction, and the later exact-title search found no resolution.

Exact unresolved remainder: Give a construction of a legal move sequence for every h>=3, with a proof that the recursive construction terminates at the root, or exhibit a height h and an invariant proving that no root-gathering sequence exists. For any individual-height computation, provide the complete move list and replay it with exact frog counts and graph distances; finite height checks alone do not settle the universal target.
