Yes, but i want to do that for all sets, not just combinations of 9 at a time.
Yes, I meant that it seems like you can do up to 18 and not 16 before you run out of rows

I did a prelim last night very small amount of data with max = 4

So I came up with 4 columns the way I was playing around (for N = 4)

C(4,1)__C(4,2)___C(4,3)___C(4,4)
1______1,2_______1,2,3___1,2,3,4
2______1,3_______1,2,4
3 _____1,4_______1,3,4
4 _____2,3_______2,3,4
_______2,4
_______3,4

I set it up so that I could just input N and it will (eventually) generate the N columns and the 'whole bunch of' rows (that's a technical Excel term )

It's an interesting problem
