OEIS Sequences

A convolution triangle of numbers generalizing Pascal's triangle A007318. A49326

Numbers k such that S(k)=d(k), where S(k) is the Kempner function (A002034) and d(k) is the number of divisors of k (A000005). A73307

Numbers n such that number of divisors of n divides S(n), the Kempner function A002034. A73413

Numbers k whose smallest prime factor index is equal to the number of distinct prime factors of k and whose largest prime factor index is equal to the number of prime factors of k counted with multiplicity. A393102

a(1) = 1. For n > 1, a(n) = a(n-1) if n is prime, a(n) = a(n-1)/n if n is composite and divides a(n-1) else a(n) = n·a(n-1). A88304

a(n) = binomial(n+2,3)*5³. A141480

Generated by sieving the natural numbers: keep the smallest remaining number k and take out its k-th successor l as well as the l-th successor m of l, the m-th successor of m and so on. Then start again from the next remaining number. A56875
