142857 is an Interesting Number

A couple of days ago I got this interesting number, 142857, via email. I performed a Google search on the number and I was surprised to see so many returns - 190,000. It even has its own wiki page. For additional information, here is the wiki page for this cyclic number - 142857.
Below is the email.

I want to let you know a weird number which is 142857. Why?

142857 X 1 = 142857
142857 X 2 = 285714
142857 X 3 = 428571
142857 X 4 = 571428
142857 X 5 = 714285
142857 X 6 = 857142
See, the answers show all same numbers with different position.
142857 X 7 = 999999
142 + 857 = 999
14 + 28 + 57 = 99

142857 X 142857 = 20408122449

20408 + 122449 = 142857

Interesting, huh?
