OEIS Sequences

Factorial base exp-function: digits in factorial base representation of n become the exponents of successive prime factors whose product a(n) is. A276076
a(n) = A276086(A003415(n)), where A003415 is the arithmetic derivative, and A276086 is the primorial base exp-function. A327859
Numbers with exactly 3 distinct odd prime divisors {3,5,7}. A147576
a(n) = A276086(σ(n)), where A276086 is the primorial base exp-function, and σ is the sum of divisors function. A388031
a(n) = 15·n2. A64761
If A327928(n) > 0, a(n) = A276086(n), otherwise a(n) = A003415(n). A327963
Integers k such that k = Sum k/(pi + j), where pi are the prime factors of k (with multiplicity). Case j = 1. A380889
a(n) = gcd(A260443(n), A260443(n+1)). A277198
Twisted variant of A276086 indexed by A328626. A328627
