Someone answered 0.  It is small, it does work./

dumbcow · Answer

it doesn't exist or its 0
sqrt(n/2) is never an integer for n>0

radar · Answer

Hey dumbcow that is true, so the only 0 could be the answer!

radar · Answer

Apparently that is not true.  the answer is now posted on the original post and it is a very large number.

sqrt (n/2) is never an integer is an erroneous assumption.  
$$\sqrt{18\over 2}$$ is just one example.
