Find the number n such that the following alphanumeric equation:

   KYOTO
   KYOTO
 + KYOTO
   TOKYO

has a solution in the base-n number system.

(Each letter in the equation denotes a digit in this system, and different letters denote different digits)

thanks to some computer hackery, n=9, giving the following possible combinations:
y=3 t=4 k=1
y=3 t=7 k=2
y=6 t=5 k=1
y=6 t=8 k=2

if I do some actual thinking there's probably a reason for this...
