(a) Consider the word "post". I want you to compute the number of different possible anagrams of "post", ignoring for the moment whether they are actual English words or not. What I mean is to compute the number of four-letter strings that use each letter just once.

(b) Draw a graph to figure out the list of all possible anagrams of "post".

(c) Which of these strings are actual English words?

(d) Go to the Internet Anagram Server and see if you can find an interesting anagram of your name. If you can't find one, you can add some other words or honorifics to your name.

(e) How do you suppose the Anagram Server works?
