Why mathemagic is fun

[|gridley|]

perfect number consist of:
a figure (like 6)
the sum of all figures it can be devided by sums up to the figure itself.
to take as an example the previously mentioned.
(1 is incuded)
6 can be devided by 1 2 and 3 (the number itself does not count)
1+2+3 = 6

28 can be devided by 1 2 4 7 14
1 + 2 + 4 + 7 + 14 = 28

Phytagoras invented some intersting things as well

13 03 02 16
08 10 11 05
12 06 07 09
01 15 14 04

At first sight maybe nothing interesting.
But if you take a closer look you will notice:
There are 16 different numbers
All horizontal lines equal 34
All vertical lines equal 34
All diagonal lines equal 34
If you devide the 'square' into squares of 4 numbers, they all equal 34

This is one of the reasons why mathemagic is more interesting then the 'a^ + b^ = c ^'


FYI only

This reminds me of the magic square riddle thing posted by Agent_Steal

I tried writing a program to solve that, but it only solved like half of it, so I had to go through by hand and figure it out. Maybe I'll try again and see if I can make a program that solves it all the way. Interesting post |gridley|, thanks for sharing.
