Question:
(i) Consider the following recursive definition of 3-PERMUTATION:
Rule 1 123 is a 3-PERMUTATION.
Rule 2 If xyz is a 3-PERMUTATION, then so are zyx and yzx.
Show that there are six different 3-PERMUTATIONs.
(ii) Consider the following recursive definition of 4-PERMUTATION:
Rule 1 1234 is a 4-PERMUTATION.
Rule 2 If xyzw is a 4-PERMUTATION, then so are wzyx and yzwx.
How many 4-PERMUTATIONs are there (by this definition)?
