Five terms, five operations. Same parameters for any number of entities.
Step by step
Permutation equivariance
Drag a token to a new slot (or shuffle). The bar values travel with their color — the model recomputes, and each entity gets back exactly its own output, just reordered.
Entity-count invariance
Slide N from 3 to 20. Watch the parameter badge above — it never moves.
This one operator, with one fixed parameter count, is applied to every entity, in every primitive, at every step — for 3 entities or 20.
