The algebra of essential relations on a finite set
... (c) The left action of Σ on the set of all essential relations is free. Proof : (a) If R factorizes through a set of cardinality smaller than Card(X), then so does ∆σ R. The converse follows similarly using multiplication by ∆σ−1 . (b) This follows from (a) by taking R = ∆ (which is essential by Pro ...
