During past years author worked with block-wise 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. Few days back, we presented bordered magic squares of odd number blocks. 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. This we have done with two different types of magic squares of order 9. Higher order examples can be seen in Excel file attached with the work. The total work is up to order 144.
