MAYBE

We are left with following problem, upon which TcT provides the
certificate MAYBE.

Strict Trs:
  { select(x', revprefix, Cons(x, xs)) ->
    mapconsapp(x',
               permute(revapp(revprefix, Cons(x, xs))),
               select(x, Cons(x', revprefix), xs))
  , select(x, revprefix, Nil()) ->
    mapconsapp(x, permute(revapp(revprefix, Nil())), Nil())
  , mapconsapp(x', Cons(x, xs), rest) ->
    Cons(Cons(x', x), mapconsapp(x', xs, rest))
  , mapconsapp(x, Nil(), rest) -> rest
  , permute(Cons(x, xs)) -> select(x, Nil(), xs)
  , permute(Nil()) -> Cons(Nil(), Nil())
  , revapp(Cons(x, xs), rest) -> revapp(xs, Cons(x, rest))
  , revapp(Nil(), rest) -> rest
  , goal(xs) -> permute(xs) }
