Lemma centropy4_swap_2_4 (A B C D E : finType) (X : {RV P -> A}) (W : {RV P -> B}) (Y : {RV P -> C}) (Z : {RV P -> D}) (V : {RV P -> E}) : `H(X | [% W, Y, Z, V]) = `H(X | [% W, V, Z, Y]).

Description

Swap 2nd and 4th positions in 4-variable conditioning: H(X | W,Y,Z,V) = H(X | W,V,Z,Y). Used for reordering Alice's view components.
