 Compact Plus 16x16 Magic Square




Connection of the Sub-Squares
The large square is divided into 16 sub-squares of 4 x 4.
Each sub-square is connected to all the others, both horizontally and vertically.
With the help of the key values, these sub-squares can be mirrored.

Key Values
Key values are the sum of two numbers from the square and always consist of two values. Together, they ultimately connect all numbers with each other.
Because each key value consists of two pairs, this involves a total of four numbers.
The average value of four numbers in a 16 x 16 square is always 514 (the magic sum 2056 divided by 4).

The key values are calculated using a calculation value, which depends on the size of the magic square.
In this example, the square is 16 x 16:
16 x 16 = 256.
The value 256 represents the difference between two numbers that together add up to 514.
The first key values that arise from this are: 129 and 385 (together 514).

Calculation Values
The first calculation value is 256.
After that, this value is repeatedly divided by 2, which gives the following sequence:
256 – 128 – 64 – 32 – 16 – 8 – 4 – 2

These calculation values lead to the following key values:

  • 256 → 129 – 385
  • 128 → 193 – 321
  • 64 → 225 – 289
  • 32 → 241 – 273
  • 16 → 249 – 265
  • 8 → 253 – 261
  • 4 → 255 – 259
  • 2 → 256 – 258

Use of the Key Values
The key values can be applied in different orders.
Depending on the chosen order, a different magic square will be created each time.
In the attached example, a different order has been used.

 

Connection of the Sub-Squares

Horizontal

Sub-square 1 and 2 are connected by the key values 253-261. As well as block 3 and 4.

Sub- square 1 and 3 are connected by the key values 225-289. As well as block 2 and 4.

Sub- square 1 and 4 are connected by the key values 129-385. As well as block 2 and 3.

Vertical

Sub-square 1 and 2 are connected by the key values 249-265. As well as block 3 and 4.

Sub- square 1 and 3 are connected by the key values 241-273. As well as block 2 and 4.

Sub- square 1 and 4 are connected by the key values 193-321. As well as block 2 and 3.

 

Constructing the first 2x2 square.

The starting point is always the number 1. Here at first position.

Generating the horizontal number by the key values 256-258. In this case 256.

Which gives the number 255 = 256-1.

Generating the vertical number by the key values 255-259. In this case 255.

Which gives the number 254 = 255-1.

The last number can the generated horizontal of vertical.

258-254= 4 or 259-255= 4

Magic Square - 8 x 8

 This is a new version of an 8x8 square. 


It is really special because of a huge set of numbers. (the sum of 2 numbers)
For example in the first row:
32 + 1 = 33
1 +63 = 64
63 + 34 = 97
34 + 30 = 64
30 + 3 = 33
3 + 61 = 64
61 + 36 = 97

This repeats in all the rows with the pattern:
1    33-64-97-64-33-64-97
2    97-66-33-66-97-66-33

In the columns the pattern is:
1    69-57-61-57-69-57-61
2    61-73-69-73-61-73-69

And of course all the other aspects of a magic square:
The sum of each row and column is 260 (and 130 for half of it).
The sum of each 2x2 set of numbers is 130.
All diagonals are 260

Labyrinth

A magic square with in de centre the lowest numbers 1 -256.
The numbers are organised from 256 till 1. It follows a path like al labyrint with 1 as the middle.

The square is magic because the sum of the numers in each row, column and all diagonals are the same: 131104


Here below only the center

Franklin in a magic square

The square is magic because the sum of the numbers in each row, column and all diagonals are the same: 131104

This 128x128 magic square is divided in 16 area.

The lowest of highest number in each area is white and and the opposite full colored. The other numbers are ordered in between, so slowly it goes from white to the specific color. 

And this is the result

The square is magic because the sum of the numbers in each row, column and all diagonals are the same: 131104

This 128x128 magic square is divided in 16 area.

The lowest of highest number in each area is white and and the opposite full colored. The other numbers are ordered in between, so slowly it goes from white to the specific color. 

And this is the result

Einstein

The square is magic because the sum of the numbers in each row, column and all diagonals are the same: 131104

I like the experiment!
In this 128x128 magic square the lowest numbers 1-1024 are in the centre.
This numbers are coded in grayscale.
Number 1 is white and number 1014 is black. The other numbers are ordered in between, so slowly it goes from white to black. How bigger the number the more black.

And this is the result


A very special Magic Square

A magic square with in de centre the lowest numbers 1 -256.
The numbers are organised so that 1-4 are in the centre. 
Around there is a layer from the numbers 5 -16.
In the next layer around the numbers 17-36
And so on:
37-64
65-100
etc and the last (outside) layer 193-256

The square is magic because the sum of the numbers in each row, column and all diagonals are the same: 131104

The extra in this square is that in this centre the 2 by 2 squares are connected
The sum of the middle 2x2 square: 10
1+2+3+4
The sum 2x2 squares of the layer around is 34
16+7+10+1 and 8+15+2+9 and 12+3+14+5 and 4+11+6+13
The sum of de 2x2 squares in the layer around is 82
25+18+23+16 and33+34+7+8 and 17+26+15+24 and 9+30+11+32 etc
in the next layers the sum of the 2x2 squares are:
162 - 274 - 418 - 594 and 802

The centre with the layers
and the total 64x64 square
