alefszámokkal
Alefszámmal, also known as aleph numbers, are a sequence of numbers that represent the cardinalities of infinite well-ordered sets. The first infinite cardinal number is aleph-null, denoted as $\aleph_0$, which is the cardinality of the set of natural numbers. This means that any set that can be put into a one-to-one correspondence with the natural numbers has cardinality $\aleph_0$. Examples include the set of integers and the set of rational numbers.
The next aleph number, aleph-one, denoted as $\aleph_1$, is the smallest cardinal number greater than $\aleph_0$.
In general, the sequence of aleph numbers is defined recursively. For any ordinal number $\alpha$, the aleph
