Product of Permutations
The applet below serves a demonstration for the product of permutations. It displays two permutations, say f and g, of numbers
(fg)(k) = g(f(k)),
so that the left permutation is carried out first. (To emphasize this fact, (fg)(k) is often written as kfg.)
The elements of the two permutations are clickable: clicking on two elements in a sequence in either of the permutations multiplies that permutation by a transposition of the two elements.
