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 odd number multiples of 3, 5, 7, 9 and 11.  These are based on different sums of magic squares of order 3, 5, 7, 9 and 11. This work is for multiples of 13.  This we have done with 25 different types of magic squares of order 13. This work brings only up to magic squares of order 52 multiples of 13. Higher order examples can be seen in Excel files attached with the work. The total work is up to magic squares of order 130.
