I have no idea how one could find this out.

    Yes: Five has four letters. Nine has four letters.

    There are no more.

    If you meant to ask if there are any more whole numbers with the same number of letters in the name as the number, then the answer is no. It is fairly simple to check - you only have to look at the numbers 0-30 before it becomes clear no other number will fit this pattern.

    If you went into fractions like 20.12325 then there will be many numbers where all the letters added would get close but the fraction itself would mean you couldn’t quite reach the exact number as you can’t have fractions of letters.

    If you included negative numbers then “minus eleven” has 11 letters. Minus thirteen has 13 letters. It seems to again break down once you go beyond 13, and its dodgy to include negative numbers as you can’t have negative letters.

    So, no.

    I don’t know in English, but in Spanish the word for five, Cinco, has five letters.

      I was able to come up with a list of similar scenarios for various languages using a simple formula in LibreOffice Calc: =LEN(A2)=ROW(A2)-1 (row 1 being a header row)

      Danish To 2
      Danish Tre 3
      Danish Fire 4
      Dutch Vier 4
      English Four 4
      Finnish Viisi 5
      French N/A N/A
      German Vier 4
      Indonesian N/A N/A
      Italian Tre 3
      Norwegian To 2
      Norwegian Tre 3
      Norwegian Fire 4
      Polish N/A N/A

      Sorry but whenever I see this symbols only thing I can think of CFT(d-orbital splitting). Because one time I asked my friend about CFT he used this symbols.

      Oh! Now I understand what that other commenter was talking about by ‘matching of letters to the numbers’ or something along those lines.

    It’s the only one in English unless you allow things like “The absolute value of -20”.
