Question 1073139
There are 10 symbols available.
Since each word has 10 symbols,
all available symbols will be used.
If all 10 symbols were distinguishable from one another,
you could make {{{10!=3628800}}} .
However, there are
3 *,
2 @,
4 #, and 1 $.
Secretly marking the repeat symbols,
in a way only you could notice,
you would realize that
interchanging the {{{2}}} @ you can make
{{{2!=2}}} copies of each word that look identical to everyone else.
Similarly, interchanging only the {{{3}}} *,
you can make {{{3!=6}}} versions of each word that only you can distinguish,
and you can make {{{4!=24}}} versions of each word by playing with the # symbols.
Playing with all of the repeated symbols,
you could make {{{2!*3!*4!=2*6*24=288}}} versions of each word.
So, although you would distinguish among {{{288}}} replicates of each word,
to see {{{3628800}}} different strings of characters,
there would be only
{{{3628800/288=highlight(12600)}}} different words.
