In this work we shall consider **four equal sum cornered magic squares** to bring different types of magic squares of orders 16, 20, 24 and 28. are constructed with **four equal sums cornered magic squares**. As explained above these are of **equal sums in pairs except in corners.**

These are made with the help of script by H. White (Downloads (budshaw.ca) – *NestedCornerRectangles*)).

Let’s start with magic squares of order 16. In this case, we have considered four equal sums magic squares of order 8.

### Magic Squares of order 16

The last two magic squares are made with magic rectangles of orders **8×10** and **6×8**

### Magic Squares of Order 20

The last three magic squares are made with magic embedding **cornered magic squares** of order 6 in double digits magic squares of order 10.

### Magic Squares of Order 24

Below are three examples of magic squares made with embedded cornered magic squares of order 8 in magic squares of order 12.

### Magic Squares of Order 28

Below are three examples of magic squares made with **embedded cornered magic squares** of order 10 in magic squares of order 14.
