Explanation 28x28 magic square

The 28x28 magic square is an odd multiple of 4. A Franklin panmagic 28x28 square does not exist (a Franklin [not pan]magic square can be constructed with help of computer programming).

Construction methods

Methods to construct the 28x28 magic square are:

• Medjig
• Composite, Simple
• Composite, AxB compact
• Composite, Matroesjka
• Composite, Prop. (1) a
• Composite, Prop. (1) b
• Symmetric transformation (Liki)
• Basic key method (ultra magic)
• Most perfect transformation
• Khajuraho method
• Basic pattern method (1)
• Basic key method (most perfect)
• Sudoku method (2)
• 26x26 in 28x28 (1)
• 26x26 in 28x28 (2)
• Concentric

The medjig magic square gives a simple 28x28 magic square.

Composite simple gives a panmagic 28x28 square.

Composite AxB compact, composite Matroesjka, composite proportional (1)a, 26x26 in 28x28 and concentric are 'specials'

Symmetric transformation and basic key method (ultra magic) leads to ultra magic 28x28 squares.

The remaining methods lead to most perfect magic 28x28 squares.
