I would like to get all unique permutations of a sequence (e.g.
{1,2,3,4,5,6,7,8,9,10,11,12,13}) with the constraint that all sequences
that have an opposite ordering are not included (e.g. {13, 12,
11,10,9,8,6,5,4,3,2,1}) would not be included.
Are there some Mathematica commands that can be used to efficiently
generate these permutations?
