%N A117943 A self-generating sequence: Let A = (a(1), a(2), ...) be the sequence. 
               A is characterized by the properties that (i) a(1) = 0, a(2) = 1; 
               (ii) if the terms a(3), a(6), a(9), a(12) ... are deleted, the remaining 
               sequence is the same as A; (iii) the deleted terms also form the 
               sequence A.
%C A117943 A super-fractal? Might also be called a lizard sequence (une suite du 
               l\'{e}zard) because it grows back from its tail.
%C A117943 Terms were computed by Gilles Sadowski.
