sup3exmid.ex	|- ( ( u C_ RR /\ E. w w e. u /\ E. x e. RR A. y e. u y <_ x ) -> E. x e. RR ( A. y e. u -. x < y /\ A. y e. RR ( y < x -> E. z e. u y < z ) ) )

Assertion

Ref	Expression
sup3exmid	|- DECID ph

Distinct variable groups:   x, z   ph, u, w   ph, x, y, z, u

Proof of Theorem sup3exmid

Dummy variables a b j k are mutually distinct and distinct from all other variables.
