%N Expected number of distinct squares visited by a knight's random walk on an infinite chessboard after n steps, normalized to give an integer.
%C Based on A326954/A326955.
%C a(0)=1; for n>0, a(n) = (A326954(n)/A326955(n))*2^(3*n-3). (It is only a conjecture that this is always an integer).
%Y Cf. A326954, A326955.
%K nonn
