[Help-gsl] permutation

[Eric Germaneau]

Hello,

I'd like to find out all possible combinations of {1,2,3,4} set. There 
are actually 1024 i think.
I'm trying to use "permutaions" from GSL but I do not get out all of them.
For example if I ask combination os {0,1} set the result is: 0 1 ; 1 0
In fact 1 1 and 0 0 are missing ....
Does someone has an idea hoe to do that?
Thanks in advance,
Regards,

                       Eric.
