%S 2,3,4,10,3,42,12,706

%N Number of maximum independent sets in the 2-Fibonacci digraph of order n.

%C See Dalfó and Fiol (2019) or A360000 for the definition of the 2-Fibonacci graph.

%C The loop at node 0 is disregarded, so 0 is allowed in the independent sets.

%H C. Dalfó and M. A. Fiol, <a href="https://arxiv.org/abs/1909.06766">On d-Fibonacci digraphs</a>, arXiv:1909.06766 [math.CO], 2019.
