Hi Johnmx
Thanks for the interesting question. I hope you have 186624 cars in
order to use all these license plates!
I was a bit unclear on whether you wanted permutations with 7 spaces
or permutations with 8 spaces. You say "7" in your question but your
examples have 8.
I was going to ask for clarification but then I thought, "hey, if I'm
doing one I might as well do the other!"
So both are listed at:
http://www.geocities.com/blink_williams/
There are 36 possible characters for each "wildcard" spot on the
license plate:
1234567890abcdefghijklmnopqrstuvwxyz
A license plate with 7 characters there are three different ways in
which "aruba" can be surrounded by characters (the character 'x'
designates a wildcard spot):
xxaruba
xarubax
arubaxx
For each arrangement there are 36 x 36 possible license plates: 1296
So this means that for a 7 character plate there are 3 x 1296 or 3888
possibilities.
A license plate with 8 characters there are four different ways in
which "aruba" can be surrounded by characters (the character 'x'
designates a wildcard spot):
xxxaruba
xxarubax
xarubaxx
arubaxxx
For each arrangement there are 36 x 36 x 36 possible license plates:
46656
So this means that for a 8 character plate there are 4 x 46656 or
186624 possibilities.
There is some change that my interpretation of your question differs
from what you had in mind. For example, perhaps you didnt want to
include zero as a possible character. If this is the case, please
request clarification and I will correct and repost the list of
permutations. Also request clarification if you would like a
different format for the list of alternatives.
Thanks,
Blinkwilliams |

In the last paragraph of my answer there is a typo. I write, "There is
some *change* that my interpretation of your question differs...." Of
course what I meant to write was, "There is some *chance* that my
interpretation of your question differs...."
Apologies for any confusion,

Blink --
Thank you for your answer.
But the request was for the permutations/combinations themselves.
That's why the examples were given (aruba123, etc)and that's why the
answer was requested in digital form (to cope with the volume of
options).
What shall we do?

Blink --
An additional point while we sort this out: that's why we articulated
the question as "list the permutations and combinations".
Let's work this out together.

Hi Johnmx-
As I note in my original answer, I list actual permutations at:
http://www.geocities.com/blink_williams/
Click on that link and you will find two text files containing a list
of the permutations: one is for 7 characters and the other is for 8
characters. You can either view the text files by clicking on the
link "aruba7.txt" or "aruba8.txt" or you can download the files by
right-clicking on the links and selecting "save target as". If you
are having any trouble accessing these files please let me know
through the 'request clarification' feature and I will respond
immediately.
If for some reason, I'm still not understanding your request, please
let me know and I'll act immediately to remedy the situation.
Thanks for your patience and do not hestitate to request further
clarification if needed.
All the best,
Blinkwilliams-ga
