Permutation Braid, 4 Unique Objects

Pull the slider to show the braid and permutations of the objects. Permutations printed in light gray are duplicates.

Thanks to Bill Mill's idea for this visualization of permutations (http://billmill.org/permvis.html). The computation is done using either the permutation formula (4!/3!) or the combination formula (C(4,3))(C(1,1)).
