# How Mathmeticians Get All Those Chicks

By Deane Barker on November 11, 2005

every number has its own significance: You *need* to know why all these numbers are significant. Really, you do.

- 6 is the smallest perfect number.
- 25 is the smallest square that can be written as a sum of 2 squares.
- 3367 is the smallest number which can be written as the difference of 2 cubes in 3 ways.
- 4062 is the smallest number with the property that its first 8 multiples contain the digit 2.
- 4095 = 111111111111 in base 2.
- 5005 is the smallest palindromic product of 4 consecutive primes.

Do any of you use StumbleUpon? I do, and I found a better version of this months ago: http://www.stetson.edu/~efriedma/numbers.html .

Oh, be sure to add me on StumbleUpon if you use it. I’m “masterzora” on there.
