OEIS Sequences

Completely multiplicative with a(prime(k)) = prime(k+1). A3961

Primorial base exp-function: digits in primorial base representation of n become the exponents of successive prime factors whose product a(n) is. A276086

The Doudna sequence: write n-1 in binary; power of prime(k) in a(n) is # of 1's that are followed by k-1 0's. A5940

a(0)=1. a(n) = p(A000120(n)) * ∏_{m=1..A000120(n)} p(m)^A163510(n,m), where p(m) is the m-th prime. A163511
