Alefszámok
Alefszámok, often translated as aleph numbers, are a sequence of numbers used in set theory to represent the cardinalities of infinite sets. They are denoted by the Hebrew letter aleph ($\aleph$) followed by an ordinal number subscript. The first aleph number, $\aleph_0$, represents the cardinality of the set of natural numbers, which is the smallest infinite cardinality. This means that any set whose elements can be put into a one-to-one correspondence with the natural numbers has cardinality $\aleph_0$.
The next aleph number, $\aleph_1$, represents the smallest cardinality strictly greater than $\aleph_0$. The continuum hypothesis
Subsequent aleph numbers, such as $\aleph_2$, $\aleph_3$, and so on, represent increasingly larger infinite cardinalities. The
