SUMMARY
A generator in a group is an element that can produce every element of the group through its powers. In the context of the group (Z_28,⊕), the identity element is a straightforward example of a non-generator. Additionally, any element that is a factor of 28, such as 2, 4, 7, or 14, also serves as a non-generator in this cyclic group.
PREREQUISITES
- Understanding of group theory concepts, specifically cyclic groups.
- Familiarity with the notation of modular arithmetic, particularly Z_n.
