BTW, before you get into this exercise, familiarize yourself with the
hazards of -sort-, as documented in

Betreff: st: sort by permutation
I have a sample of N individuals belonging to 4 sub-groups g1, g2, g3,
g4. I would like to sort my sample of size N in 24 different
manners, corresponding to all possible permutations of my group
variable
say, {g1,g2,g3,g4}, {g1,g3,g2,g4} {g1,g3,g4,g2}...etc.
Taking a simple exemple for N=10. I have
id group
1 1
2 1
3 2
4 2
5 2
6 3
7 3
8 4
9 4
10 4
one possible sorting among 24 could be
id group
1 1
2 1
6 3
7 3
3 2
4 2
5 2
8 4
9 4
10 4
any help is apreciated
