Description

This work brings universal magic squares of order 17 to 32. By universal we understand that the magic squares are upside-down and mirror looking independent of magic square sums. The work for the digits as 2 and 5. For the digits  1,8 and 6,9 is given in another papers. The same work can be extended for the digits  0,1 and  0,8. Similar kind of work for orders 3-16 is already done before.  The block-wise constructions for the magic squares of orders 18, 20, 21, 24, 25, 27, 28, 30 and 32 are also included. Moreover, in case of orders 25 and 32, we have  bimagic squares, while for the case of order 24, it is semi-bimagic square. The whole work is without use of any programming language. It is just based on the number's combinations.
