If we take the
ribbon by the ends and pull it out
This number has the peculiarity that, if we
multiply it by any one of the numbers, 2, 3, 4, 5,
7, 8, or 9, we get
exactly the same number in the circle, starting from a different
For example, multiply by 4, and the product 2352941176470588, which
starts from the dart in the circle.
So, if we multiply by 3, we get the
same result starting from the star.
Now, the puzzle is to place a
different arrangement of figures on the ribbon that will produce
results when so multiplied; only the 0 and the 7 appearing at the ends
the ribbon must not be removed.
