Web$\aleph_0$ is the cardinality of the set $\{0,1,2,3,\ldots\}$ of all finite cardinalities. These are linearly ordered in a way that gives each of them only finitely many predecessors. $\aleph_1$ is the cardinality of the set of all countable ordinals. $\frak{c}$ is the same as $2^{\aleph_0}$ and is the cardinality of the set of all real numbers. In the above section, "cardinality" of a set was defined functionally. In other words, it was not defined as a specific object itself. However, such an object can be defined as follows. The relation of having the same cardinality is called equinumerosity, and this is an equivalence relation on the class of all sets. The equivalence class of a set A under this relation, then, consists of all those sets which have the same cardinality as A. There are two ways to define the "cardinalit…
