Rearranging Letters in a Word

For this piece of coursework I am going to investigate the number of

different ways I can write a word, re-arranging the letters without

having any repeats of the sequence.

After I have finished my investigations I will try and use my findings

to draw together a formula which I could then use to find out how many

ways a word can be written for any chosen word.

My initial step is to write the name 'EMMA' with as many different

arrangements I can find.

======================================================================

Part 1

======

1) EMMA

=======

7) MAME

=======

2)

==

The total number of arrangements for the name 'EMMA' is 12.

EMAM

8) MEAM

=======

3) EAMM

=======

9) MAEM

=======

4) MMEA

=======

10) AEMM

========

5) MMAE

=======

11) AMEM

========

6) MEMA

=======

12) AMME

========

Next I am again going to try a 4 letter word, but this time without

repeats (no 2 letters the same) in it.

I predict that a 4 letter without repeats will have a lot more letter

arrangements than the name EMMA which has 'M' repeated.

Part 2- I have chosen the name ANDY.

=====================================================================

1) ANDY

=======

9) NYAD

=======

17) DYNA

========

2) ANYD

=======

10) NYDA

========

18) DYAN

========

The total number of arrangements for the name ANDY is 24.

3) ADYN

11) NDYA

========

19) YADN

========

4) ADNY

=======

12) NDAY

========
