Problem
colored beads are placed on a necklace (circular ring) such that each bead is adjacent to two others. The beads are labeled 
, 
, 
, 
around the circle in order. Two beads 
and 
, where 
and 
are non-negative integers, satisfy 
if and only if the color of is the same as the color of . Given that there exists no non-negative integer 
and positive integer 
such that 
, where all subscripts are taken 
, find the minimum number of different colors of beads on the necklace.
