Check out -selectvars- from SSC. Also -tuples- from SSC.

I have a doubt about the command "joinby". I need to make all the
possible combinations of 15 variables in groups of 10, a total of 3003
results. Each one of the 10 variables should be different and the 3003
results must be different and not repeated. My problem is when I use
joinby, I have results with variables repeated and also observations
with the same variables but in different order. For example:
variable1 variable2 variable3 variable4 variable5 variable6 variable7
variable8 variable9 variable10
variable1 variable2 variable3 variable4 variable5 variable6 variable7
variable8 variable10 variable9
variable1 variable2 variable3 variable4 variable5 variable6 variable8
variable7 variable10 variable9
