Reply To: Is a NI needed?
Here is another case where it is better to understand the rules instead of searching for an example that fits the question. The rule you are looking for is Rule II, Sec.11.e which sends you back to sections 9 to see if any of the "Use of the Numeric Indicator" rules apply.
a: Is the numeral at the beginning of a braille line or after a space? No.
b: Is the numeral following a punctuation mark? No.
c-g do not apply here.
Section 9a is the rule to understand. In essence, a numeric indicator is not needed here because the numeral is not preceded by a space (in braille).
