Figured Magic Squares of Order 28: A Systematic Procedure

For the first time we are introducing the idea of magic squares by figures. This work brings magic squares of order 28. In some cases, the idea of construction is explained. It is based on external borders made by magic squares or bordered magic rectangles. Then inner blocks are previously known magic squares of smaller orders. The inicial work is up to order 30. Further orders shall be written in futures. The lack of numbers in figures is due to the fact that the readers can also try to complete them in their own ways. Otherwise, the readers can see the results in the author’s other works. Up to order 20 the results can be seen here. Below is a list of work of even order magic squares from orders 6 to 30.
