Numerical Symmetry.

Also fun is.. 142857

142857 x 1 = 142857
142857 x 2 = 285714
142857 x 3 = 428571
142857 x 4 = 571428
and so on and so on until..
142857 x 7 = 999999
and then.. when it you thought it was unique enough.
142857 x 8 = 1142856 (1 + 142856 = 142857)
so you can try any number..
142857 x 152 = 21714264 (21 + 714264 = 142857)

seeing this post reminded me of that number, which reminded me of my kooky old math teacher.

Nice!!!
