Theorem releupa 23895
Description: The set  ( V EulPaths  E ) of all Eulerian paths on  <. V ,  E >. is a set of pairs by our definition of an Eulerian path, and so is a relation. (Contributed by Mario Carneiro, 12-Mar-2015.)
Assertion
Ref Expression
releupa  |-  Rel  ( V EulPaths  E )

Proof of Theorem releupa
Dummy variables  e 
f  k  n  p  v are mutually distinct and distinct from all other variables.
