• 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), (-1, 0, 0), (0, 1, -1), (1, -1, 1), (1, 0, 1)}.at n=10A148929
• Primes p such that p - d and p + d are also primes, where d is the smallest nonzero digit of p.at n=7A245878
• Table read by antidiagonals: T(n,k) is the number of paths in the Z X Z grid joining (0,0) and (n,k) each of whose steps increases the Euclidean distance to the origin and has coordinates with absolute value at most 1.at n=37A346538
