Q restricted rewrite system:
The TRS R consists of the following rules:

   active(eq(0, 0)) -> mark(true)
   active(eq(s(X), s(Y))) -> mark(eq(X, Y))
   active(eq(X, Y)) -> mark(false)
   active(inf(X)) -> mark(cons(X, inf(s(X))))
   active(take(0, X)) -> mark(nil)
   active(take(s(X), cons(Y, L))) -> mark(cons(Y, take(X, L)))
   active(length(nil)) -> mark(0)
   active(length(cons(X, L))) -> mark(s(length(L)))
   active(inf(X)) -> inf(active(X))
   active(take(X1, X2)) -> take(active(X1), X2)
   active(take(X1, X2)) -> take(X1, active(X2))
   active(length(X)) -> length(active(X))
   inf(mark(X)) -> mark(inf(X))
   take(mark(X1), X2) -> mark(take(X1, X2))
   take(X1, mark(X2)) -> mark(take(X1, X2))
   length(mark(X)) -> mark(length(X))
   proper(eq(X1, X2)) -> eq(proper(X1), proper(X2))
   proper(0) -> ok(0)
   proper(true) -> ok(true)
   proper(s(X)) -> s(proper(X))
   proper(false) -> ok(false)
   proper(inf(X)) -> inf(proper(X))
   proper(cons(X1, X2)) -> cons(proper(X1), proper(X2))
   proper(take(X1, X2)) -> take(proper(X1), proper(X2))
   proper(nil) -> ok(nil)
   proper(length(X)) -> length(proper(X))
   eq(ok(X1), ok(X2)) -> ok(eq(X1, X2))
   s(ok(X)) -> ok(s(X))
   inf(ok(X)) -> ok(inf(X))
   cons(ok(X1), ok(X2)) -> ok(cons(X1, X2))
   take(ok(X1), ok(X2)) -> ok(take(X1, X2))
   length(ok(X)) -> ok(length(X))
   top(mark(X)) -> top(proper(X))
   top(ok(X)) -> top(active(X))

The set Q consists of the following terms:

   active(eq(x0, x1))
   active(inf(x0))
   active(take(x0, x1))
   active(length(x0))
   inf(mark(x0))
   take(mark(x0), x1)
   take(x0, mark(x1))
   length(mark(x0))
   proper(eq(x0, x1))
   proper(0)
   proper(true)
   proper(s(x0))
   proper(false)
   proper(inf(x0))
   proper(cons(x0, x1))
   proper(take(x0, x1))
   proper(nil)
   proper(length(x0))
   eq(ok(x0), ok(x1))
   s(ok(x0))
   inf(ok(x0))
   cons(ok(x0), ok(x1))
   take(ok(x0), ok(x1))
   length(ok(x0))
   top(mark(x0))
   top(ok(x0))
