Description

During past years author worked with bordered magic squares of even number blocks. These are based on equal sums magic squares of orders 4, 6, 8, 10, etc.  This type of work is an extension of classical bordered magic squares. In case of multiples of 4, the extension is made for pandiagonal magic squares. The work is extended for the multiples of orders 6, 8, etc.  Recently, author worked on multiples of 3, 5 and 7. These are based on different sums of magic squares of order 3, 5 and 7. This work is for multiples of 9. It is  revised and extended verison of previous work. This we have done with eleven different types of magic squares of order 9. Examples are written only up to order 35. Higher order examples can be seen in Excel file attached with the work. The total work is up to order 144.
