Block-Structured Prime Magic Squares: Orders 44 to 47

This work bring different ways of representing prime magic squares. These are of types: blocks, block-bordered, concentric, nested, etc. This work is for the orders 44 to 47. For prime magic squares of orders 6 to 43 refer author's work in the reference list. In case of prime magic squares of orders 47, the compositions of order 45 are applied over 47 considering single-layer border representing as block-bordered prime magic squares, with internal blocks based on different compositions of prime magic squares of order 46. Even though the magic square of order 46 is not prime but there is only one way to represent in blocks, i.e., multiples of 23. Due to this we considered more examples using compostitions of prime magic square of order 44 as internal block.  This is also available on author's web-site.
