Dalet (also spelled dāleth or Daleth) is the fourth letter of the Hebrew alphabet. In set theory, mathematicians originally intended to use daleth to represent the fourth transfinite cardinal numbers.[1] The name "dalet" is connected to the word "delet", meaning "door". It also corresponds to the letter "delta" in the Greek alphabet.[2]
