Infinite sets. Sets can be finite or infinite. Furthermore, infinite sets can be countable or uncountable. Countable. Any infinite set that can be paired with the natural numbers in a one-to-one correspondence such that each of the elements in the set can be identified one at a time is a countably infinite set.
