Aleph

Aleph, or alef, א, is the first letter of the Hebrew alphabet.


In mathematics, Aleph usually refers to a series of numbers used to represent the cardinality of infinite sets. For example,

<math>\aleph_0</math> is the number of numbers in the set of rational numbers or integers.
<math>\aleph_1</math> is the next largest cardinal number after <math>\aleph_0</math>
<math>\aleph_2</math> is the next largest cardinal number after <math>\aleph_1</math>
and so on...


Aleph is also one of the most advanced systems for inductive logic programming.


Aleph is also the name of a religion in Japan, formerly known as Aum Shinrikyo.
