Hello hello.

I need a list that shows all the ways that the numbers 1-6 can combine between themselves and with another group of the same set of numbers. Order does not matter and (this is what I assume is the tricky part) only groups of (2,3,4, and 5) numbers should be considered. I have no idea how to calculate this and I figured it was probably trivial for the math whizzes around here.

Is this with or without replacement? i.e. can you have 11, 22, 33, etc.?

Excellent question I didn't think of. I wouldn't want that.

I'm not quite sure that I understood your problem correctly, but I think you're asking for every combination of numbers in the set {1, 2, 3, 4, 5, 6} of lengths 2 through 5, without repeats. If I'm right, then this should be the list, which I wrote a simple program to generate (and you could also do this by hand fairly quickly). If you want to see the code, which I highly doubt you do, I can post it later.
Code:
Length 2: 1 2 1 3 1 4 1 5 1 6 2 3 2 4 2 5 2 6 3 4 3 5 3 6 4 5 4 6 5 6 Length 3: 1 2 3 1 2 4 1 2 5 1 2 6 1 3 4 1 3 5 1 3 6 1 4 5 1 4 6 1 5 6 2 3 4 2 3 5 2 3 6 2 4 5 2 4 6 2 5 6 3 4 5 3 4 6 3 5 6 4 5 6 Length 4: 1 2 3 4 1 2 3 5 1 2 3 6 1 2 4 5 1 2 4 6 1 2 5 6 1 3 4 5 1 3 4 6 1 3 5 6 1 4 5 6 2 3 4 5 2 3 4 6 2 3 5 6 2 4 5 6 3 4 5 6 Length 5: 1 2 3 4 5 1 2 3 4 6 1 2 3 5 6 1 2 4 5 6 1 3 4 5 6 2 3 4 5 6

Lucid,
Thanks for the reply. That shows all the ways that the numbers 1-6 can combine between themselves of lengths 2-5. For my whole problem to be solved I also need that group of combinations compared in the same way against another group of the same set of numbers. I'm terrible at word problems so I hope I'm phrasing this clearly.

Rather than abstracting it, tell us what you're actually trying to do and we might understand the question better. Right now I'm unclear what you mean - it might make more sense with some context.

Yeah, I'm having trouble understanding what you want to do with the second set. You stated that you don't want any repeated numbers in the list (like 11, or 11451) so I don't see what the second set would add to the list, seeing as they are the same numbers. A clarification of what the second set signifies would be nice, as well as putting the problem in context as Bryson suggested.
