I was so proud about this.
Not too much now.
This post was supposed to be written and published at 6 AM.
But I had to go to the Sunday mass, so… there goes the excitement.
Anyway, let’s pretend that I am still very excited about this.
Yesterday, I saw Albrecht Durer’s magic square.
It was awesome.
For all of you who don’t know what a magic square is, well, it is simply a square with consecutive numbers on it.
The magic lies within the fact that the sum of each row, column, and diagonal are the same.
Albrecht Durer’s magic square, however, is more than that.
Not only does it have the usual properties of a magic square, it also has an equal sum of the numbers on its center square (which consists of four smaller squares), and all four quadrant squares.
Moreover, the number 1514 on the bottom row is actually the year the square was created.
Impressed, I decided to make my own.
After a gruesome long night, I was finally able to create what I think is a
BETTER magic square.
Like any other magic squares, the sum of each row, column, and diagonal are the same.
But that’s only the half of it.
You will also find that the sum of
EVERY four adjacent squares that form a larger square is the same.
Take any
four squares that form a larger square you want, and the sum of the numbers will be the same.
UPDATE
From the initial square, I was also able to derive no less than 96 squares that follow the same rules (kinda takes away the value actually).
I divide them into three groups called batches.
For the sake of space, I'm only presenting one square per batch.
Batch 21-13/25-9
2 16 5 11
13 3 10 8
12 6 15 1
7 9 4 14
Batch 19-15/25-9
7 14 1 12
9 4 15 6
16 5 10 3
2 11 8 13
Batch 18-16/25-9
4 9 7 14
15 6 12 1
10 3 13 8
5 16 2 11
But Albrecht Durer’s square has the production year on it, you might say.
Well, my squares are only 4 by 4, which means the largest number is 16. There’s no number 20 to create the year 2009.
But, as far as dates are concerned, here is the list of ALL possible dates you can get from my squares:

Hooray!
- The End –
Okay, now I’m going back to my mattress.
