Everything about Beth number
Infinite Cardinal number
In mathematics, particularly in set theory, the beth numbers form a certain (unset) sequence of infinite cardinal numbers, conventionally written, where is the Hebrew letter beth. The beth numbers are related to the aleph numbers, but unless the generalized continuum hypothesis is true, there are numbers indexed by that are not indexed by. On the other hand, beth numbers are cofinal in plain Zermelo-Fraenkel set theory. Wikipedia →
