Recently, the author revised and improved the block-wise<\/strong> bordered<\/strong> magic squares multiples of even number blocks<\/strong>. This means, multiples of 4, 6, 8, etc. The work is up to order 20. These works can be accessed at the following links.

Author also worked with odd number blocks. The work is for multiples of order 3, 5, 7, 9, 11 and 13. See the links below:

The advantage in studying block-wise bordered<\/strong> magic squares is that when we remove external borders, still we left with magic squares with sequential entries. <\/p>\n\n\n\n

We observe that the above study of even order blocks starting from 4. Recently, author studied the double digit<\/strong> or two digits<\/strong> borders resulting in interesting magic squares. These studies can be accessed at the following link:
1. Two Digits Bordered Magic Squares Multiples of 4: Orders 8 to 24<\/a>.
2. Two Digits Bordered Magic Squares of Orders 28 and 32<\/a>.
3. Two digits Bordered Magic Squares of Order 36.<\/a>
4. Two digits Bordered Magic Squares of Order 40.<\/a>

The work is for the order of type 4k+2, where k>1, i.e., for the orders 10, 14, 18, 22, 26, 28, 30 and 32 can be access at the following links:
1. Two digits Bordered Magic Squares of Orders 10, 14, 18 and 22<\/a>.
2. Two digits Bordered Magic Squares o<\/a>f Orders 26 and 30<\/a>.
3. Two Digits Bordered Magic Squares of Orders 28 and 32.<\/a>

Some studies towards cornered magic squares are also made. See the following links:
1. Cornered Magic Squares of Orders 5 to 10<\/a>.
2. Cornered Magic Squares of Orders 11 to 13<\/a>.
3. Cornered Magic Squares of Orders 14 to 24<\/a>.<\/p>\n\n\n\n

Below are examples of bordered magic squares multiples of order 19. These examples are only for the magic squares of orders 19 and 57. Total work is with 42 different types of magic squares of order 19. PDF files<\/strong> of magic squares of order 19 and 57 are also attached. In the end there are excel files<\/strong> of whole the up to order 133 multiples of 19. <\/p>\n\n\n\n

Magic Squares of Order 19<\/h4>\n\n\n\n

Below are 42 magic square of order 19. We have used these magic squares to bring bordered magic squares up to order 133 as multiples of 19.<\/p>\n\n\n\n
