(c) From figures (i), (ii) and (iii), we concludethat 3, 4, 2 and 6 lie adjacent to 5. Therefore,1 must lie opposite 5. From figures (i), (iii) and (iv), we concludethat 4, 5, 6 and 1 lie adjacent to 3. Therefore,2 must lie opposite 3. Now, we have 1opposite 5 and 2 opposite 3. Hence, 4 mustlie opposite 6.
