labelTotally ordered set is monotonically normalOrder topology is completely normal
note`OrderTopology.completelyNormalSpace` (and `t5Space`) prove a linearly ordered space with the order topology is completely normal.`OrderTopology.completelyNormalSpace` (and `t5Space`) prove a linearly ordered space with the order topology is completely normal. (The article also asserts the stronger 'monotonically normal' result, which is not in Mathlib.)
