## Summary

In mathematics, and more specifically number theory, the **superfactorial** of a positive [[integer|0C4JS9RF5M]] $n$ is the product of the first $n$ [[factorials|0XWG0JGDFW]]. They are a special case of the Jordan–Pólya numbers, which are products of arbitrary collections of factorials.
