In set theory, the term "code" can refer to a specific structure or concept used to represent sets or elements in a formal way. It may particularly relate to the idea of coding or encoding mathematical objects such as sets, sequences, or functions into a particular format that can be easily manipulated or analyzed. One common concept related to coding in set theory is the use of **ordinal numbers** and **cardinal numbers** for coding sets.
