A cool number


Not really a joke ... just a tiny bit of fun.


142857 is a cyclic number - its digits always appear in the same order but will rotate around when multiplied by any number from 1 to 6:


142857 x 1 = 142857


142857 x 2 = 285714


142857 x 3 = 428571


142857 x 4 = 571428


142857 x 5 = 714285


142857 x 6 = 857142


Pretty cool, huh? Now multiply 142857 by 7.
