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

Code:

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
