Ferrers diagrams

A Ferrers diagram is a visual way to represent a partition of a number, displaying how it can be broken into parts. Imagine arranging dots or squares in rows, with each row's length equal to a part of the partition, starting with the longest at the top. The rows are aligned to the left, creating a staircase-like shape. This diagram makes it easy to see how a number is divided into smaller sums and is useful in combinatorics and mathematics for visualizing and analyzing partitions and related concepts.
