%N A195107 Fractalization of the fractal sequence A004736. Interspersion fractally induced by A004736.
%C A195107 See A194959 for a discussion of fractalization and the interspersion fractally induced by a sequence. The sequence A004736 is the fractal sequence obtained by concatenating the segments 1; 2,1; 3,2,1; 4,3,2,1;...
