 Residue-class-wise affine group

The residue-class-wise affine group is a mathematical concept that arises in the context of group theory, specifically in relation to affine transformations and modular arithmetic. To understand it better, let's break down the terms involved: 1. **Affine Transformation**: An affine transformation can be viewed as a function that maps points from one vector space to another while preserving points, straight lines, and planes.
