• Numbers k such that pi(k) divides k.at n=40A057809
• Consider the sequence {b(m)} of nonprimes; sequence gives values of m where gcd{m, b(m)} increases.at n=40A058011
• Squarefree kernel of (n*prime(n))*(n+prime(n)).at n=19A066197
• 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, 1), (0, 1, -1), (1, -1, -1), (1, 0, 1)}.at n=10A148812
