Investigating Different Arrangements of Letters of Words

I will be investigating the different arrangements of letters of

words, which don't have any identical letters in them and those that

do. Then I will try and find a formula that can calculate the total

arrangements of letters of any word, which does not have any identical

letters in it. I will also try and find a formula to find the total

arrangements of words, which have some identical letters in them.

Firstly I will look at those words, which have no identical letters in

them and then work out a formula that can find the total arrangements

of letters in them. So I will begin by finding the total arrangements

of a one-lettered word to finding the total arrangements of a

four-lettered word. Thereafter I will try and predict the total

arrangements of a five-lettered word and then I will check if I was

correct by finding the total arrangements of it's letters

Part 1

======

One-lettered word

A =1

There is only one arrangement for a one-lettered word.

Two-lettered word

WE

EW =2

There are two different arrangements for a two-lettered word whose

letters are all different.

Three-lettered word

CAR CRA

ACR ARC =6

RCA RAC

There are six different arrangement for a three-lettered word whose

letters are all different.

Four-lettered word

LUCY LUYC LYUC LYCU LCYU LCUY

ULCY ULYC UCLY UCYL UYCL UYLC

CLUY CLYU CULY CUYL CYUL CYLU

YUCL YULC YCUL YCLU YLCU YLUC =24

There are 24 different arrangement for a four-lettered word whose

letters are all different.

In a four-lettered word the total arrangements is 24 because in the

word LUCY there are 4 letters and you can only get 6 different

arrangements with each letter at the beginning. So the calculations

for this would be 4 x 6 = 24.

For a five-lettered word there are 24 different arrangements with each
