  2. O is above C and H and below I which is to the left of B.
  3. M is to the left of D and below G.
  4. N is below E, above D and to the right of A which is above G, below P and to the right of O and F.
Note: “Above/below” refers to two letters in the same column. “Left of / right of” refers to two letters in the same row.
