Finding the maximum numbers of ways to arrange a word.

An anthropologist discovers an isolated tribe who has written an alphabet that contains only six letters (call the letters A, B, C, D, E, and F). The tribe has a taboo against using the same letter twice in the same word, it's never done. If each different sequence of letters constitutes a different word in the language, what is the maximum number of six-letter words that the language can employ?

Beauty and Aesthetic Value

Below I am asking three separate questions, the first question is just a difference in opinion. The second and third question I need some explanation as I am confused about the differences. My thought to question one is no they all all different in their own way, but I would like your opinion and why you feel that way. Are persons, natural landscapes, and objects of art all "beautiful" in the same way? Is art criticism based upon aesthetic value? Could you explain why please. Could you give me an example of criteria to show that something has aesthetic value.
