actually (I think) it should be - depending on how "strict" your definition/goal is - pick your poison :
Code:
BEGIN {
  FS=OFS=","
}
{
   t2[$2]=$1
   t3[$3]=$1
   t3t[$1]=$3
}
END {
  for (i in t2)
    print t2[i], i, t3t[t2[i]], (i in t3)?t3[i]:( t3t[t2[i]] in t2)?t2[t3t[t2[i]]]:""
}

resulting in:
Code:
1,10,8,2
2,12,10,3
3,13,12,2
4,14,14,4
5,15,16,6
6,16,18,5
