There is only one null set. Two sets are equal if they contain the exact same elements although their order can be different. For example: Set Q is inhabited, and contains the following three elements: x, y, z Q = {x, y, z} Set Ø (Null Set) is empty. The null set provides a foundation for building a formal theory of numbers. You can see the TCW and TCNB values are 0 and NULL, as they should be. The null set makes it possible to explicitly define the results of operations on certain sets that would otherwise not be explicitly definable.
