Universal Magic and Bimagic Squares of Orders 3 to 32 Using 2 and 5

This work brings, magic squares of order 3 to 32 just with two digits in such a way that the magic squares are upside-down and mirror looking independent of magic sums. These types of magic squares we call as universal magic squares. This is done only with two digits 2 and 5. In this case the numbers 2 and 5 are written in digital form. In mirror looking case, 2 becomes 5 and 5 as 2.

The works for the digits 1 and 8, and 6 and 9 are given separately. For the case of 6 and 9, we have only upside-down magic squares. In this case, when making 180 degrees rotation 6 becomes 9 and 9 as 6. In case of order 3 it is semi-magic square. The work is divided in two papers. One from order 3 to 16 and another for order 17 to 32. See the links below:

The first link is for all the three cases, while the second link in only for the digits 2 and 5. The magic squares of orders 8, 9, 16, 25 and 32 are also written in bimagic squares. While for the case of order 24, the result is semi-bimagic. The block-wise constructions of magic squares of orders 8, 9, 12, 15, 16, 18, 20, 21, 24, 25, 27, 28, 30 and 32 are also given. The cases of orders 15, 21 and 27 are semi-magic squares. The whole work is without use of any programming language. The work is done just with number’s combinations. For the orders 3 to 16, the palindromic magic squares are also given.

There are 4-digits in each cell for the magic squares of orders 3 and 4. 6-digits in each cell for the magic squares of orders 5 to 8. 8-digits in each cell for the magic squares of order 9 to 16. 10-digits in each cell for the magic squares of order 17 to 32. For the semi-bimagic and bimagic squares of orders 24, 25 and 32, there are 12-digits in each cell.

Similar kind of work for the order 33 to 64, and for the orders 65 to 128 is under preparation.
