Well, now, that does raise some questions. Is 'X' written with 2
toothpicks or 4? (Apparently 2 from your data, but it isn't obvious a
priori.) Are 'C' and 'D' available? If so, how many toothpicks do
they use? I could see 2 and 3, respectively, or 0 and 1 (with the
curved parts represented some other way); or maybe you bend the
toothpicks and get 1 and 2. 'M' presumable uses 4. 5000 may be
expressed with 5 M's, or with an underlined or overlined 'V'; in the
latter case, it would presumably require 3 toothpicks. Then for 15000,
do we use a single toothpick to underline both the 'X' and the 'V', or
are they separate?

P.S. Just my opinion, but -- ick. Bad enough that it's another Roman
numeral sequence, but posing problems of how to define it on top of
that ....

Integers which, when written in Roman numbers with toothpicks,
are divisible by the quantity of toothpicks they use.
