Theorem exmidapne 7616

Description: Excluded middle implies there is only one tight apartness on any class, namely negated equality. (Contributed by Jim Kingdon, 14-Feb-2025.)

Assertion

Ref	Expression
exmidapne	|- (EXMID -> ( R TAp A <-> R = { <. u , v >. | ( ( u e. A /\ v e. A ) /\ u =/= v ) } ) )

Distinct variable group:   u, A, v

Allowed substitution hints:   R( v, u)

Proof of Theorem exmidapne

Dummy variables p x y z are mutually distinct and distinct from all other variables.
