The first round of creating permutations would be made fixing the `m` as the prefix of the string, and then creating permutations of the rest of the string, `achine`. For the rest of the string, permutations continue in the same way. One letter is added to the prefix, maybe the `c`, so the prefix becomes `mc`. Then, each of the permutations of `ahine` is concatenated to the prefix.
