单词	Finite
释义	finite A set $S$ is finite if there exists a natural number $n$ and a bijection from $S$ to $n$ . Note that we are using the set theoretic definition of natural number, under which the natural number $n$ equals the set $\\{0,1,2,\\ldots,n-1\\}$ . If there exists such an $n$ , then it is unique, and we call $n$ the cardinality of $S$ . Equivalently, a set $S$ is finite if and only if there is no bijection between $S$ and any proper subset of $S$ .
