The advantage in studying **block-wise bordered** magic squares is that when we remove external borders, still we left with magic squares with sequential entries.

We observe that the above study of even order blocks starting from 4. Recently, author studied the **double digit** or **two digits** 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.

2. Two Digits Bordered Magic Squares of Orders 28 and 32.

3. Two digits Bordered Magic Squares of Order 36.

4. Two digits Bordered Magic Squares of Order 40.

The work is for the order of type 4k+2, where k>1, i.e., for the orders 10, 14, 18, 22, 26 and 30 can be access at the following links:

1. Two digits Bordered Magic Squares of Orders 10, 14, 18 and 22.

2. Two digits Bordered Magic Squares of Orders 26 and 30.

3. Two Digits Bordered Magic Squares of Orders 28 and 32.

Some studies towards cornered magic squares are also made. See the following links:

1. Cornered Magic Squares of Orders 5 to 10.

2. Cornered Magic Squares of Orders 11 to 13.

3. Cornered Magic Squares of Orders 14 to 24.

Below are examples of bordered magic squares multiples of order 11 up to order 55. Total we worked with 20 different types of magic squares of order 11. Up to order 55 pdf files of each order are attached for download. **Excel files** of whole work are also attached at the end.
