Table of n, a(n) for n=0..48.

EXAMPLE

"1" is in the sequence because if you replace each letter of "un" ("one") by its rank in the alphabet you get the string 2114 which contains at least a "1".

"trois" (3) produces the string 201815919 which contains no "3" - thus "3" is not a "french self-ranked number".
