Name

The word: Name, may be thought of as a kind of number, which may or may not be related to certain quantity. However, by just having a name, such as $\emptyset$, it already implied the connotation of cardinality and ordinality in a greater context.

Name as a Kind of Number

In number theory, or in mathematics in general, a name can be adopted as a static or invariant symbol to represent a discrete number, or even just a discrete concept.
