I am having Sage generate an array of lists for me, but I do not want it to give me the lists that have all of the same elements. For example, if Sage gives me
[1 2 3 4]
[2 3 4 1]
[1 3 4 2]
I only want Sage to give me [1 2 3 4]. I want to create a new array with these non-repeated lists. How do I do that? Thank you!
