Thus, aleph-null is the first infinite cardinal, and denotes the cardinality of the natural numbers (or any countably infinite set, i.e. of cardinality w), and aleph-one is the next cardinal number, standing for the next size of infinity, and so on.

The number of natural numbers is designated by À0. "À" is the first letter of the Hebrew alphabet, pronounced Aleph. "À0" is pronounced Aleph-null or Aleph-nought. ... Now you know how many natural numbers there are: À0. But this is not profound. So far we've only invented a name (numeral) for the number of natural numbers.

This cardinality is denoted by the capital Aleph, with a subscript of zero. It is read "Aleph null". Aleph is the first letter of the Hebrew alphabet. Theorem: ... The order of a group is defined as its cardinality. Why a different name? Groups had order long before Cantor invented the concept of cardinality.
