English: A diagram of a process that creates a superpermutation of 3 symbols from a superpermutation of 2 symbols. First, the superpermutation is separated into its individual permutations. Then, each permutation is placed next to a copy of itself with a third new symbol added in between. Lastly, each structure is placed next to each other with adjacent symbols merged if they are the same. This process is infinitely repeatable. When resulting in superpermutations five or less, the superpermutation is the smallest possible.
