• 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, -1), (-1, -1, 1), (-1, 1, 0), (1, 0, -1), (1, 1, 1)}.at n=9A149552
• Smallest number m such that A212813(m) = n.at n=14A212911
• Primes of the form k!3-2187, where k!3 is the triple factorial number (A007661).at n=2A289822
• The first of two consecutive primes the sum of which is equal to the sum of two consecutive pentagonal numbers.at n=4A298464
