The empty set is unique, and that is why it is entirely appropriate to talk about theempty set, rather than an empty set. This makes the empty set distinct from other sets. There are infinitely many sets with one element in them.
The sets {a}, {1}, {b} and {123} each have one element, and so they are equivalent to one another. Since the elements themselves are different from one another, the sets are not equal.
There is nothing special about the examples above each having one element. With one exception, for any counting number or infinity, there are infinitely many sets of that size.
