the upper bound..

multiply both sides by 2^ 1998
rhs becomes (odd prod.).2^999 / 999!
this is nothing but 1998C999...

now it becomes something like a = 2nCn / 2^2n.
rhs is always less than 1/2n+1..( 2^2n/2nCn > 2n+1 )
hence it becomes a>1/1999...

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


Kriteesh..
