Inspired by wolfgang's post, I thought I would give my own.

2,4,3,1,6,5,7
3,7,5,6,1,8,2,4
2,7,6,3,9,4,8,5,1

1) What would it be for 10 numbers? What method am I using?

Here's another one (but it is (hopefully) harder, so I'll give all of them up to 9):

1
1,2
1,2,3
4,1,3,2
3,1,4,5,2
6,3,2,5,4,1
1,4,3,2,6,5,7
5,7,8,6,4,1,3,2
4,5,8,6,2,7,3,1,9

2) What is the order for 10 numbers? What is the method?
