[Stefan Bisitz]

Hi,

Mathematicians told me a long time ago to use a high range and only odd 
numbers to get best permutation results. Others might have more details.

If you are unsure about a good randomization, you might try "Calculate 
answers for [n] versions." on the problem testing screen - if the used 
response type is supported.
