Different Types of Magic Squares of Orders 6, 8, 10 and 12

It is revised version of author's previous work. It brings new ideas of construction of magic squares. This work is for magic squares of even orders 6, 8, 10 and 12. The ideas ideas used to bring these magic square are: bordered magic rectangles, bordered double digits magic rectangles, cornered magic rectangles, striped magic rectangles, etc. When the length and width are equal these magic rectangles becomes as magic squares.  Another idea used is of algebraic formula (a+b)^2. Here we consider small blocks of magic squares and magic rectangles, such as a^2, b^2, axb and bxa. We are able to bring 6 magic squares of order 6, 30 magic squares of order 8, 175 magic squares of order 10 and 634 magic squares of order 12. These are available in author's site, whose links are given above.
