Comments

Diacritics are ignored when computing the rank of a letter.

Spellings used for French numbers: zero, un, deux, trois, quatre, cinq, six, sept, huit, neuf, dix, onze, douze, treize, quatorze, quinze, seize, dix-sept, dix-huit, dix-neuf, vingt, vingt et un, vingt-deux, vingt-trois, vingt-quatre, vingt-cinq.

The numbers 18 and 22-25 do not occur in the sequence. - David Applegate, Sep 24 2007

There appears to be no analog in Spanish. (The requirement is that the difference between the ranks of the first two letters in the word for the number n should equal n.) - David Applegate, Sep 24 2007. There exists such a sequence (namely, 12, 13, 2, 16, 2, 14, 2, 2, 1...) if (as is standard) letter 'ñ' is granted an alphabet position, whereas digraphs such as 'll' are not. - Álvar Ibeas, Sep 18 2020
