During past years author worked with block-wise<\/strong>, bordered<\/strong> and block-bordered<\/strong> magic squares. This work make connection between block-wise<\/strong> and bordered<\/strong> magic squares. We started with block-wise bordered<\/strong> magic squares of orders 140 and 120. Based on these two big magic squares, the inner order magic squares multiples of 16 are studied. By inner orders we understand that magic squares of orders 100, 80, etc. The construction of the block-wise bordered<\/strong> magic squares multiples of 20 is based on equal sum blocks of magic squares of order 20<\/strong>. We have taken 57 different types of magic squares of order 20<\/strong>. The advantage in studying block-wise bordered<\/strong> magic squares is that when we remove external border, still we are left with magic squares with sequential entries. It is the same property of bordered<\/strong> magic squares with single digits numbers. The difference is that instead of numbers here we have blocks of equal sum magic squares of order 16. For multiples of orders 4, 6, 8, 10, 12, 14, 16 and 18 see the links below:
