👉 Undistinctness is a concept in mathematics that refers to the absence of any two distinct elements in a set, such as numbers or sets. It is often used in discussions about number theory and analysis, where it is used to compare the size of different sets, such as the size of the set {1, 2} versus the set {3, 4}. In this sense, undistinctness can be seen as a fundamental property of sets that distinguishes them from other collections
