The number 142,857 is a cyclic number, which means multiplying it by anything between 2 and 6 will result in a cyclic permutation of itself.

How about that.

Try it! It’s kind of mind-blowing. And even above six, when you multiply by seven, eight or nine, you get interesting results too:

• 7: 999999
• 8: 1142856 (the seven split and became one at front and six)
• 9: 1285713 (the four moved to the end, essentially, in two numbers)
