Domain: Plane partition statistics

Details

• Defined over PlanePartition as an expression in _x, evaluated by compute-engine — the definition IS the implementation.
• Takes a PlanePartition and nothing else — it reads values against their positions, or walks the orbits, so it needs the bijection. Applying it to a bare list is a type error, not a wrong answer.
• FindStat's St001920.

Definition

Epsil, as the implementation runs it.
