markings & permutations   
Hi
Here is the situation:
I mark scissors and look for a system which is both practical and with
many permutations.
They way I want to do it is as following:
At the pivot, i.e. the hole through which the pivot screw goes, at the
inside of one of the blades, I want to do as follows:
The hole has a N, S, W and E or 12 o clock, 3, 6, and 9 o clock. At
each of these 4 positions I have space to make three

small holes with a diamond drill - i.e. either nothing or 1 or 2 or 3
- total of 4 markings.
My question is what would be the most efficient way of 'populating'
these areas with either empty spaces or holes and what

is the limit of my permutations around one hole - obviously without
any duplications?
Regards
Gabriel Smit

You have 4 positions, each of which can have one of 4 markings.  So you 
have 4^4 = 256 possible markings.
