Equipment

This is what I have to work with, as you can see there are diamonds, clubs, spades and hearts. I haven't quite figured out if there are a certain number of each that do a certain number of things, for example, I cannot see any example of two diamonds being adjacent to one another either as outer or inner shapes. However, the spades and clubs appear this way once each, one way or another. It seems that part of the problem is that there are so many combinations for the pieces themselves, that this is only one fairly random set. So far, I just can't find a pattern. I might have to learn each piece individually.
