Homework Statement
My online notes stated that it |g| = |G| where g is an element of G then |G| is cyclic.
Can somebody help me understand why this is true?

A cyclic group is a type of algebraic structure in which all elements can be generated by a single element, called a generator, through repeated application of the group's operation. It is denoted by (G, ∙) where G is the group and ∙ is the operation.
A cyclic group is different from other groups because it has a specific structure and property. Unlike other groups, all elements in a cyclic group can be generated by a single element, making it a simpler and more predictable structure.
The order of a cyclic group is the number of elements it contains. It is always finite and is equal to the number of times the generator needs to be applied to itself to generate all elements in the group. For example, if the generator is x and the order is n, then the elements in the group are x, x2, x3, ..., xn.
Yes, a cyclic group can have an infinite order. In this case, the group is called an infinite cyclic group and its elements can be generated by repeatedly applying the generator to itself an infinite number of times.
Cyclic groups can be found in many areas of mathematics and science, including number theory, abstract algebra, and physics. Some real-life examples include the group of rotations in a 2D plane, the group of integers modulo n, and the group of complex roots of unity.
