Appears in sequences

• Consider the 1-D random walk with jumps to next-nearest neighbors. Sequence gives number of paths of length n ending at origin.at n=10A092765
• First differences of A132581.at n=51A132582
• Number of walks within N^3 (the first octant of Z^3) starting at (0,0,0) and consisting of n steps taken from {(-1, -1, 0), (0, 0, -1), (0, 1, 0), (1, 0, 1), (1, 1, 0)}.at n=8A151122
• a(n) = 3*binomial(4*n,n) - 20*binomial(3*n,n) + 54*binomial(2*n,n).at n=6A357955
