OEIS Sequences

a(n) = 2·n³. A33431

Dirichlet g.f.: ∏_k>=2 1 / (1 - k^-s)^k³. A343283

a(n) = n * ∑_d∣n binomial(d+4,5)/d. A343546

Dirichlet g.f.: ∏_k>=2 (1 + k^-s)^k³. A343323

a(n) = floor(1/{(2+n⁴)^1/4}), where {} = fractional part. A184537

Numbers k such that the sum of prime factors of k (counted with multiplicity) equals four times the largest prime divisor of k. A212862

a(n) is the least k that starts a sequence of exactly n numbers on which i + ω(i) is constant, where ω = A001222 (this is BigOmega). A369228

Numbers k such that k and k+1 have the same sum of squarefree divisors, or sqf(k) = sqf(k+1), where sqf(k) = A048250(k). A63964

Numbers k such that core(k) = b(k,1)*b(k,0) where b(k,1) is the number of 1's in binary representation of k, b(k,0) the number of 0's and core(k) the squarefree part of k. A71639

Starts of runs of 3 consecutive integers in which each member of the run has at least one divisor of the form p^e with p <= e, where p is a prime. A376469
