Properties

Appears in sequences

• Numbers m such that m divides Sum_{k = 1..m} A000005(k).at n=16A050226
• Least m such that the average number of divisors of all integers from 1 to m equals n, or 0 if no such number exists.at n=12A085567
• a(0) = 1 by convention; for n>0, a(n) is the number of points in the n-th figure shown in A255011 (meaning the figure with 4n points on the perimeter).at n=16A331449
• Numbers k that divide Sum_{i=1..k} (i - d(i)), where d(n) is the number of divisors of n (A000005).at n=16A362864
• Prime numbersat n=32226
