COMMENT
|
This uses "modern" (i.e. medieval) Roman numerals; the ancient Romans did not use prefixed letters to subtract. One sometimes sees e.g. "IL" for 49, but this is not standard; the standard representation encodes each digit separately. Sequence is finite since Roman numerals are only defined up to 3999. (There is an extension using underlined letters up to 3999999, but that's still finite.) - Frank Adams-Watters (FrankTAW(AT)Netscape.net), Jul 26 2006
