keep C_ _ _ _ _ ...
next early appearing letter is C again..
so it gets CC_ _ _ _ permutations possible -- 4!..
similarly CH _ _ _ _ -4! ways again..
now CI _ _ _ _ 4! ways again..
now CN _ _ _ _ 4! ways again..
now COCHIN...u get as the next letter..
so total permutations r - 4 (4!) = 96..

Diamonds r formed under greatest pressures..
so r the champs.
Kriteesh..
