OEIS Sequences

Primorial base log-function: fully additive with a(p) = p#/p, where p# = A034386(p). A276085

Euclid numbers: 1 + product of the first n primes. A6862

Numbers obtained by reinterpreting base-2 representation of n in primorial base: a(0) = 0, a(2n) = A276154(a(n)), a(2n+1) = 1 + A276154(a(n)). A276156

a(n) = A276156(n) / A002110(A007814(n)). A328461

Numbers n such that the arithmetic derivative of A276086(n) is prime. A328233

Numbers that are sums of distinct primorial numbers, A002110, and do not have a factor of the form p^p. A328832

Pseudoprimes to base 5, written in base 5. A262102

Number of compositions (ordered partitions) of n into distinct parts >= 5. A339103

Triangle read by rows: T(n,k) = A002110(n) + A002110(k), 0 <= k <= n; sums of two primorials, not necessarily distinct. A370121

Expansion of 1/((1-x)*(1-x²)²*(1-x³)²*(1-x⁴)²*(1-x⁵)*(1-x⁶)). A45513
