• Define the generalized Pisot sequence T(a(0),a(1)) by: a(n+2) is the greatest integer such that a(n+2)/a(n+1) < a(n+1)/a(n). This is T(2,6).at n=11A018915
• a(n) is the least prime p, such that next_prime(2*p) - 2*p = 2*n - 1.at n=36A059846
• Prime averages of two successive perfect powers (A001597(k) + A001597(k+1))/2.at n=3A075455
• 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, 0, 1), (0, 0, -1), (0, 1, 0), (1, 0, 0)}.at n=10A149965
• Primes that are exactly halfway between the nearest square and the nearest cube.at n=2A233444
• Primes in A194627.at n=24A377791
