If I'm not mistaken....
....there's no six digit version.
Seven digits: 3211000
Eight: 42101000
Nine: 521001000
So here's a pattern arising.
Ten of course is yours truly.
Eleven: 72100001000
The last digit would mean something like (0 1-digit representations of 10, e.g. X, as in ISBN numbers)
Twelve: 821000001000
Thirteen: 9210000001000
And what do we do with fourteen?
If we con't use X, since it's a kind of dummy place holder in our thinking about ten through thirteen and not a real digit, I think there is no answer to fourteen. What about higher numbers?
