OEIS Sequences

MacMahon's generalized sum of divisors function. A2127

Let f(k) = exp(π*sqrt(k)); sequence gives numbers k such that ceiling(f(k)) - f(k) < 1/10³. A127022

Numbers n such that nextprime(n³)-prevprime(n³) = 4. A90121

Numbers m such that the largest digit in the decimal expansion of 1/m is 2. A341383

n is odd and sum of digits of n equals the numbers of divisors of n. A57532

a(n) = least k such that 2ⁱ*k+1 is prime for 1<=i<=n. A124417

Multiply previous term by 6 and reverse. A132078

a(n) = number of steps to reach 0 when starting from k = n³ and repeatedly applying the map that replaces k with k - A055401(k), where A055401(k) = the number of positive cubes needed to sum to k using the greedy algorithm. A261227
