In set theory, an **unfoldable cardinal** is a certain type of large cardinal. To understand unfoldable cardinals, we first need to know about the notion of **large cardinals** in general. Large cardinals are certain kinds of infinite cardinal numbers that possess strong properties, making them larger than the usual infinite cardinals (like \\(\\aleph_0\\), the cardinality of the natural numbers).
