In French also called: les nombres "évites" ou "apparés".
Could also be called les nombres "epers". - Benoit Cloitre, May 05 2003
French version of eban numbers (A006933): no "e" in name of number in French - "e" perd ("e" lost)!

Examples

			a(1) = 1 ("un"), a(2) = 3 ("trois", not "dEux")

See A233187 for a variant using strict inequality, "larger" instead of "not smaller", in the definition. See A233184 and A233185 for related English and French versions.

A variant of A233185 and the English version A233184. Whereas in the English case the use of the weak inequality would only change the first, third and fourth term (credits to H. Havermann), there are more differences between the two variants in the French version. See A233187-A233188 for German variants.
