Different Types of Magic Rectangles in Construction of Even Orders Magic Squares

Never Seen Before.

This work brings magic squares in very different way. These are based on three different types of magic rectangles:
1. Bordered Magic Rectangles:
2. Double Digits Magic Rectangles:
3. Cornered magic rectangles.

First of let’s understand these magic rectangles one by one. Removing external borders in each case still we left with lower order magic rectangles. See below few examples in each case.

1. Bordered Magic Rectangles

Below are two examples of bordered magic rectangles

Example. Bordered Magic Rectangle of Order 12×18

The entries according to colors are as follows:

2. Double Digits Magic Rectangles

Below are two examples of bordered magic rectangles

Example 1. Double Digits Magic Rectangle of Order 14×20

Except the corners, the entries entries sums are understood as

3. Cornered Magic Rectangles

Below is an example of cornered magic rectangles

Example. Cornered Magic Rectangle of Order 8×12

Let’s consider a cornered magic rectangle of order 10×24 formed by 240 sequencial entries, i.e., from 1 to 240:

Distributions in colors is as follows:

Based on ideas given above, we shall construct magic squares of order 22. These are constructed with four magic rectangles. As explained above these are of are of equal sums. These are made with the help of script by H. White (Downloads (budshaw.ca) – NestedCornerRectangles)). These kinds of magic squares are never seen in the history. There are of different styles. All the three types of magic rectangles are used to bring magic squares of order 22. See below the summary.
