Hypotheses

Ref	Expression
eloprabg.1	|- ( x = A -> ( ph <-> ps ) )
eloprabg.2	|- ( y = B -> ( ps <-> ch ) )
eloprabg.3	|- ( z = C -> ( ch <-> th ) )

Assertion

Ref	Expression
eloprabg	|- ( ( A e. V /\ B e. W /\ C e. X ) -> ( <. <. A , B >. , C >. e. { <. <. x , y >. , z >. | ph } <-> th ) )

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

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