[Reinhard Zumkeller]

leider habe ich erst nächste Woche wieder Zeit;
dann werde ich näher hinschauen; b-files zu
 A118757/8 habe ich am 6. März losgeschickt
(auf Anfrage von Franklin T. Adams-Watters).

Inwiefern beantworten die folgenden Kommentare
nicht Ihre Frage?

Gruß
Reinhard

%N A003100 Decimal Gray code for n.
%C A003100 This permutation of the non-negative integers is not
self-inverse, as
               previously claimed. The first exception is a(100) =
190, but a(190)
               = 109. - Franklin T. Adams-Watters

%C A003100 a(n) = A118757(n) for n<=100, = a(100)=A118757(100)=190,
but a(101)=191,
               A118757(101)=180. - Reinhard Zumkeller
