%N a(n) is the number of P-positions for n-modular Nim with 3 piles.

%H Tanya Khovanova and Karan Sarkar, <a href="http://arxiv.org/abs/1508.07054">P-positions in Modular Extensions to Nim</a>, arXiv:1508.07054 [math.CO], 2015.

%F a(2n+1) = A130665(2n+1).

%e P-positions of 2-modular Nim with 3 piles: (0,0,0), (1,1,1) and permutations of (0,1,2). Thus a(2) = 8.

%Y Cf. A130665, A267092.

%K nonn,more

%O 1,2
