First of, we're talking no repetition. So I thought I would just look these up when I get home, but I didn't find anything except finding the number of possible permutations, variations or combinations. I already know that part because of the formulas, but my teacher talks about some order of permutations and finding the nth permutation. Is there some sort of rule of ordering permutations? For example if we had: $\displaystyle 1 2 3 4 5$ what would be the next permutations and why?

There is no general rule for ordering permutations. You can make up your own.

Eh, sorry for the late reply, had no internet. So I guess the writers of my textbook made one up and didn't write anything about it? I mean most exercises there are about finding the nth permutation (or combination) which wouldn't make any sense if there wasn't one defined. Well I'll just cling on to the pattern I found. Thanks for the reply anyway.
