Pull the slider to form the braid and list the permutations.
Duplicate permutations are shown in light gray letters.
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!/(2!2!)) or the combination formula ((4C2)(2C2)).
