*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 1. Bordered Magic Rectangle of Order 12×18**

The entries according to colors are as follows:

#### Example 2. Bordered Magic Rectangle of Order 6×16

The entries according to colors are as follows:

More details are given in author’s recent work:

### 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

**Example 2. Double Digits Magic Rectangle of Order 12×18**

Except the corners, the entries **entries sums** are understood as

After reorganizing the **internal magic rectangle of order 4×16**, we have the following **double digits magic rectangle**:

### 3. Cornered Magic Rectangles

Below are two examples of cornered magic rectangles

**Example 1. Cornered Magic Rectangle of Order 8×12**

Let’s consider a cornered magic rectangle of order **8×12** formed by 96 sequencial entries, i.e., from 1 to 96:

Distributions in colors as follows:

**Example 2. 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 as follows:

More details are given in author’s recent work:

**Inder J. Taneja,**Different Types of Magic Rectangles,**Zenodo**, September 04, 2023, pp. 1-26, https://doi.org/10.5281/zenodo.8316719.

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:

### Magic Squares of Order 26

Initially below are two **double digits** and **cornered magic squares** of order 26:

### 1. Bordered Magic Rectangles and

Magic Squares of Order 26

Below are examples of **magic squares of order 26** centered in magic squares of order 6, 10, 14 and 18 respectively. These are constructed with four equal sums **bordered magic rectangles **of orders **10×16, 8×18, 6×20** and **4×22** respectively.

More examples are in **pdf file **attached at the end of work.

### 2. Double Digits Magic Rectangles and

Magic Squares of Order 26

Below are examples of **magic squares of order 26** centered in magic squares of order 6, 10 and 14 respectively. These are constructed with four equal sums **bordered magic rectangles **of orders **10×16, 8×18 **and** 6×20 **respectively.

More examples are in **pdf file **attached at the end of work.

In this case we don’t have magic square of order 26 **centered in magic square of order 18** having four equal sums** double digits magic rectangles**.

### 3. Cornered Magic Rectangles and

Magic Squares of Order 26: First Type

Below are examples of **magic squares of order 26** centered in magic squares of order 6, 10, 14 and 18 respectively. These are constructed with four equal sums **cornered magic rectangles **of orders **10×16, 8×18, 6×20** and **4×22** respectively.

### 3. Cornered Magic Rectangles and

Magic Squares of Order 26: Second Type

Below are examples of **magic squares of order 26** centered in magic squares of order 6, 10 and 14 respectively. These are constructed with four equal sums **cornered magic rectangles **of orders **10×16, 8×18 **and** 6×20** respectively.

### 3. Cornered Magic Rectangles and

Magic Squares of Order 26: Third Type

Below are examples of **magic squares of order 26** centered in magic squares of order 6, 10 and 14 respectively. These are constructed with four equal sums **cornered magic rectangles **of orders **10×16, 8×18 **and** 6×20** respectively.

### PDF File of Magic Squares of Order 26

Below is a pdf file of 294 magic squares of order 26 for download. These are constructed with 4 **equal sums magic rectangles of three types** as explained above. Magic squares numbers 1 and 2 are basic.
