• Number of walks on cubic lattice.at n=32A005571
• Minimal covering numbers.at n=68A160559
• Consider coefficients U(m,L,k) defined by the identity Sum_{k=1..L} Sum_{j=0..m} A302971(m,j)/A304042(m,j) * k^j * (T-k)^j = Sum_{k=0..m} (-1)^(m-k) * U(m,L,k) * T^k that holds for all positive integers L,m,T. This sequence gives 4-column table read by rows, where the n-th row lists coefficients U(3,n,k) for k = 0, 1, 2, 3; n >= 1.at n=39A316387
• Expansion of 140*x*(1 + 4*x + x^2) / (1 - x)^5.at n=9A317984
