Aleph Zadik Aleph was created in 1924-05.

Aleph Samach was created in 1893.

An aleph number is any of a sequence of numbers used to represent the cardinality of infinite sets, denoted by the Hebrew letter aleph.

Aleph is the name of a Hebrew letter, not a person. All 150 psalms in the Bible include the letter aleph (א).

Also infinity. If you are concerned about the size of sets, it is a higher-level (larger) infinity. For example, 2 to the power aleph-zero, or aleph-zero to the power aleph-zero, is equal to aleph-one.
