How are the orders in a cyclic group related?

Featured Replies

G is a cyclic group of order n generated by an element g, G = {e, g, g2, ..., gn-1). It can be also generated by its other element h = gk, G = {e, h, h2, ..., hn-1}. How are the k and n related?

No, the group generated by another element is a subgroup of G, not necessarily G itself.

k is a factor of n (or perhaps a multiple of a factor of n).

"It can be also generated by its other element" is a given.

Then k and n are relatively prime.

It is also sufficient, right?
