Theorem ovmpox 6217

Description: The value of an operation class abstraction. Variant of ovmpoga 6218 which does not require D and x to be distinct. (Contributed by Jeff Madsen, 10-Jun-2010.) (Revised by Mario Carneiro, 20-Dec-2013.)

Hypotheses

Ref	Expression
ovmpox.1	|- ( ( x = A /\ y = B ) -> R = S )
ovmpox.2	|- ( x = A -> D = L )
ovmpox.3	|- F = ( x e. C , y e. D |-> R )

Assertion

Ref	Expression
ovmpox	|- ( ( A e. C /\ B e. L /\ S e. H ) -> ( A F B ) = S )

Distinct variable groups:   x, y, A   x, B, y   x, C, y   x, L, y   x, S, y

Allowed substitution hints:   D( x, y)   R( x, y)   F( x, y)   H( x, y)
