# Rectangles in latin squares

## TL;DR

This paper explores the minimal modifications needed to transform one Latin square into another, focusing on changing at least four entries and providing methods to identify and implement these changes.

## Contribution

It introduces a method for finding and changing four entries in a Latin square to obtain another, advancing understanding of Latin square transformations.

## Key findings

- Minimum of four entries must be changed to obtain a different Latin square.
- Provides a systematic way to identify these entries.
- Demonstrates how to perform the changes effectively.

## Abstract

To get another from a given latin square, we have to change at least 4 entries. We show how to find these entries and how to change them.
