The two examples below show the limit of the combinatory wall.
They give a starting idea of why the random generation of word has poor interest in brand naming.

The number of different possible combinations of words for a given length :

Although these numbers seem to be large enough, if you subtract all uninteresting and identical combinations these number reduce greatly. (Don't ask miracles with 3 or 4 letters)

If you try to scramble all the possible places of  letters in  the word COCA-COLA, you will get 335634 words. (guess how many words will be identical).

For instance if you try with COCA you will get these 22 words:

coca coac ccao ccoa caoc caco ocac occa oacc occa ocac caco caoc ccoa ccao coac coca acoc acco aocc acco acoc

in which only 13 are unique:

coca coac ccao caco oacc occa ocac caoc ccoa aocc acco acoc

Same work scrambling the word TWINGO.
Just try to find out where is the word "TWINGO" (720 combinations!)
(don't cheat using the browser search facilities)
Boring, isn't it?
