 Primitive element (finite field)

In the context of finite fields (also known as Galois fields), a **primitive element** is an element that generates the multiplicative group of the field. To understand this concept clearly, let's start with some basics about finite fields: 1. **Finite Fields**: A finite field \( \mathbb{F}_{q} \) is a field with a finite number of elements, where \( q \) is a power of a prime number, i.e.
