%e Replacing one by one the terms of the sequence with:

%e 0=Z E=1 R=2 O=3 U=4 N=5 D=2 X=7 T=8 I=9 S=10 Q=11 A=12 C=13 P=14 H=15 F=16

%e gives :

%e Z,E,R,O,U,N,D,E,U,X,T,R,O,I,S,Q,U,A,T,R,E,C,I,N,Q,S,I,X,U,N,Q,U,A,T,R,E,S,E,P,T,H,U,I,T,D,E,U,X,T,R,O,I,S,N,E,U,F,D,I,X,O,N,Z,E,Q,U,A,T,R,E,D,O,U,Z,E,H,U,I,T,

%e ... which spells the sequence itself.

%e This is the lexicographically first sequence of this kind.

%Y Cf. A316910 for the English version.
