GFq×
GFq× is a mathematical structure representing the multiplicative group of the finite field Fq. A finite field Fq, where q is a prime power, consists of q elements and is equipped with addition and multiplication operations that behave similarly to those of integers. The notation "×" signifies the set of non-zero elements of Fq under the operation of multiplication.
The structure GFq× forms a cyclic group of order q-1. This means that all elements in GFq×
The study of GFq× is fundamental in various areas of mathematics and computer science, including abstract algebra,
