## 'Slippy Numbers' printed from http://nrich.maths.org/

The number 10112359550561797752808988764044943820224719 is
called a 'slippy number' because, when the last digit 9 is moved to
the front, the new number produced is the slippy number multiplied
by 9.

Find slippy numbers ending in 4 (a small one) and in 2 and 3
(larger ones).

Explain why the slippy number ending in 9 has a unique sequence
of digits; can there be more than one slippy number ending in
9?
