The Difference Between Infinite and Finite

[JBKlyde]

There is no repetition in any sets finite or infinite. Whether a set is finite or infinite is a matter of "how many" elements are in a set.

Simply put, if a set is finite, you can list the elements in the set and actually finish listing them. A set is infinite if you could never actually finish creating a list of the elements in it.

The natural numbers is an example of an infinite set. You can begin listing them today, say one a second, and never finish, there would always be another to add to the list. The even natural numbers is a subset of the naturals that is also infinite.
