You're right, Franklin... As always, just
after submitting I "saw" the C -- then the D...
We could exclude integers written with those
letters, but... mhâââ, this becomes too com-
plicated -- thus ugly!

Objet : [seqfan] Re: Romans with toothpicks
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
From: Eric Angelini <Eric.Angelini at kntv.be>
S = 1,2,3,6,9,10,12,20,30...
Integers which, when written in Roman numbers with toothpicks,
are divisible by the quantity of toothpicks they use.
