Authored summary

UNKNOWN as of 2026-07-31. The MathOverflow thread has zero answers. The authors' primary 2024 note states the conjecture, proves a partial result, and does not give a general solution; later checked research material still calls it unproven. Give a valid expression for every finite incomparable family and prove the construction terminates, or give a finite family for which no expression over the allowed leaves and partial operations exists.

The record cites sources for its explanation.

2Authored explanation

UNKNOWN as of 2026-07-31. The MathOverflow thread has zero answers. The authors' primary 2024 note states the conjecture, proves a partial result, and does not give a general solution; later checked research material still calls it unproven.

A complete resolution must satisfy this condition: Give a valid expression for every finite incomparable family and prove the construction terminates, or give a finite family for which no expression over the allowed leaves and partial operations exists.
