Theorem ovigg 6781

Description: The value of an operation class abstraction. Compare ovig 6782. The condition ( x e. R /\ y e. S ) is been removed. (Contributed by FL, 24-Mar-2007.) (Revised by Mario Carneiro, 19-Dec-2013.)

Hypotheses

Ref	Expression
ovigg.1	|- ( ( x = A /\ y = B /\ z = C ) -> ( ph <-> ps ) )
ovigg.4	|- E* z ph
ovigg.5	|- F = { <. <. x , y >. , z >. | ph }

Assertion

Ref	Expression
ovigg	|- ( ( A e. V /\ B e. W /\ C e. X ) -> ( ps -> ( A F B ) = C ) )

Distinct variable groups:   x, y, z, A   x, B, y, z   x, C, y, z   ps, x, y, z

Allowed substitution hints:   ph( x, y, z)   F( x, y, z)   V( x, y, z)   W( x, y, z)   X( x, y, z)
