Nathaniel Johnston, Table of n, a(n) for n = 1..3999

FORMULA

a(n) = A092196(n) - A006968(n).

EXAMPLE

a(4)=2 because old style takes four letters (IIII) versus new style's two (IV).

MAPLE

A092197 := proc(n) return length(convert(n, roman, period=early)) - length(convert(n, roman)): end: seq(A092197(n), n=1..105); # Nathaniel Johnston, May 18 2011
