Primitive root

If \(n\) is a positive integer, the integers between 1 and \(n − 1\) that are coprime to \(n\) (or equivalently, the congruence classes coprime to \(n\)) form a group with multiplication modulo n as the operation; it is denoted by Zn× and is called the group of units modulo n or the group of primitive classes modulo n. As explained in the article multiplicative group of integers modulo n, this group is cyclic if and only if n is equal to 2, 4, p^k, or 2p^k where pk is a power of an odd prime number. A generator of this cyclic group is called a primitive root modulo n, or a primitive element of Zn^×.

You still have [5] in there. On Brilliant, communicating in English is recommended.

I'll edit your comment to make a \(\sqrt{x}\). Click on edit and check that for reference.
