Description: Any one-to-one onto function determines an isomorphism with an induced relation  S. (Contributed by Mario Carneiro, 9-Mar-2013.)
Hypothesis
Ref Expression
f1oiso2.1  |-  S  =  { <. x ,  y
>.  |  ( (
x  e.  B  /\  y  e.  B )  /\  ( `' H `  x ) R ( `' H `  y ) ) }
Assertion
Ref Expression
f1oiso2  |-  ( H : A -1-1-onto-> B  ->  H  Isom  R ,  S  ( A ,  B ) )
Distinct variable groups:    x, A, y   
x, B, y    x, H, y    x, R, y
Allowed substitution hints:    S( x, y)

Proof of Theorem f1oiso2
Dummy variables  w  z are mutually distinct and distinct from all other variables.
