fixed typo
Apr 27, 2021 at 22:27 comment added LSpice In "whenever $(u, v) \le (u, v)$", should it be "whenever $(u', v') \le (u, v)$"?
Apr 27, 2021 at 22:13 comment added YCor @LSpice of course I mean "nontrivial finite", thanks for pointing out.

fixed typo, added remark
Apr 27, 2021 at 22:01 comment added LSpice Is it really Behr, or Baer? (Also, I think "nontrivial quotient" should be "nontrivial finite quotient", right, as in your comment? For example, you can quotient by the subgroup of permutations that move only finitely many elements.)
